+# ⬡ Hellion Dashboard — Changelog
+
+All notable changes per version. Format based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

+### v1.10.0 — 22.03.2026
+
+#### Themes
+
+- **3 new themes** — Satisfactory (Industrial Desert), Avorion (Deep Void) and Hellion Stealth (Tactical Recon)
+- Now **11 themes** total, each with its own accent colors, overlays and font styles
+- Satisfactory has increased board alpha (0.65) and stronger blur (12px), a deliberate choice for better readability on a visually busy background
+- Avorion uses a radial gradient overlay so the ship in the center of the image stays visible
+- Hellion Stealth is the only theme with a `border-left` hover effect in tactical scanner style
+
+---
+
+### v1.9.0 — 22.03.2026
+
+#### New Features
+
+- **Onboarding reworked** — 7 slides instead of 6, new slide explains the widget toolbar with all widgets

+- **Settings redesign** — Settings panel slimmed down to 3 sections (Widgets, Data & Help, Danger Zone)
+- **Appearance modal** — Theme picker and all display settings combined in one modal instead of spread across the panel
+- **Fixed about footer** — Developer info, license and links are now permanently visible at the bottom of the settings panel
+- **Project documentation** — `docs/architecture.md`, `docs/widget-schema.md` and `docs/patterns.md` for anyone who wants to fork or contribute

+
+#### New Features

+# Hellion Dashboard — Design & Theme System
+
+> This document is intentionally written in English. Full German/English i18n support
+> is planned for v2.0 — until then, English keeps the docs accessible to anyone
+> who wants to contribute or fork the project.
+
+---
+
+## Design Pillars
+
+| Pillar | Description |
+|---|---|
+| **Immersion** | The interface feels like a HUD floating over the scene, not a foreign object sitting on top of it |
+| **Visual Clarity** | Deliberate use of `blur` separates UI from background and reduces visual noise and cognitive load |
+| **Harmony** | Every theme pulls its colors from the dominant light sources in its background image |
+
+---
+
+## Background Images — WebP Only
+
+**All background images must be in WebP format.** This is an intentional architectural
+decision to keep storage quota usage predictable and leave room for future features
+(widgets, image references, etc.) that also compete for the 10 MB `chrome.storage` limit.
+
+JPG, PNG and other formats are not accepted, so convert before adding a theme.
+
+### Recommended Settings
+
+| Quality | When to use |
+|---|---|
+| 85 | Default, good balance of size and sharpness |
+| 80 | For images over 500 KB |
+| 90 | For images with fine details (stars, in-game UI text) |
+
+### Conversion Tools
+
+**Squoosh** (squoosh.app) — browser-based, no install, nothing gets uploaded to external servers.
+Drag in the image, pick WebP, set quality to 85, download. Done.
+
+**cwebp** (command line):
+```bash
+cwebp -q 85 input.jpg -o output.webp
+```
+
+### Current Theme Images
+
+| File | Status |
+|---|---|
+| `bg-nebula.webp` | ✅ WebP |
+| `bg-crescent.webp` | ✅ WebP |
+| `bg-event-horizon.webp` | ✅ WebP |

+
+## Anatomy of a Theme
+
+Every theme lives in `main.css` as a `[data-theme="name"]` block. Copy this template
+to add a new one:
+
+```css
+[data-theme="your-theme-name"] {
+  /* 1. ACCENTS — The light source */
+  --accent:          #HEXCODE;             /* Main color (neon/light) */
+  --accent-dim:      rgba(R, G, B, 0.12);  /* Subtle background tint */
+  --accent-glow:     rgba(R, G, B, 0.08);  /* Glow for logo & clock */
+  --border-accent:   rgba(R, G, B, 0.25);  /* Focus ring */
+
+  /* 2. BASE — The foundation */
+  --bg-primary:      #HEXCODE;             /* Darkest point in the image */
+  --bg-board:        rgba(R, G, B, 0.55);  /* Glass effect on boards */
+  --border:          rgba(R, G, B, 0.12);  /* Default border */
+
+  /* 3. TEXT — Contrast */
+  --text-primary:    #FFFFFF;              /* Readable, slightly tinted */
+  --text-secondary:  #A0A0A0;             /* Desaturated, less visual weight */
+  --text-muted:      #606060;             /* Barely visible, for hints */
+
+  /* 4. OVERLAY — Vignette */
+  --overlay-bg: radial-gradient(
+    circle at center,
+    transparent 0%,
+    var(--bg-primary) 100%
+  );
+
+  /* 5. COMPONENT COLORS */
+  --header-bg:          rgba(R, G, B, 0.94);
+  --board-hover-border: rgba(R, G, B, 0.22);
+  --toggle-on-bg:       rgba(R, G, B, 0.20);
+  --logo-shadow:        rgba(R, G, B, 0.50);
+
+  /* 6. FONTS */
+  --font-display: 'Rajdhani', sans-serif;
+  --font-body:    'Inter', sans-serif;
+}
+
+/* Theme-specific overrides */
+[data-theme="your-theme-name"] .logo        { letter-spacing: 4px; }
+[data-theme="your-theme-name"] .clock       { color: var(--accent); }
+[data-theme="your-theme-name"] .board-title { text-transform: uppercase; }
+[data-theme="your-theme-name"] .board       { backdrop-filter: blur(8px); }
+[data-theme="your-theme-name"] .bm-item:hover { background: var(--accent-dim); }
+```
+
+After adding the CSS block, register the theme in `src/js/themes.js` and add a preview entry in the theme picker.
+
+---
+
+## UI Patterns
+
+### Frosted Glass
+
+Hardware-accelerated blur for readability on complex backgrounds:
+
+```css
+backdrop-filter: blur(8px);
+```
+
+Creates depth and visual calm behind text and UI elements. Standard value is `8px`. Only increase it when the background image has a lot of fine detail that competes with the UI.
+
+### Clock Color
+
+All themes set `color: var(--accent)` on the clock element. This is a consistent
+detail across the entire theme system. Don't skip it for new themes.
+
+```css
+[data-theme="your-theme"] .clock { color: var(--accent); }
+```
+
+### Typography Hierarchy
+
+| Font | Usage |
+|---|---|
+| **Rajdhani** | Display: clock, logo, titles. Anything that should feel like a system readout |
+| **Inter** | Body: bookmark titles, lists, interactive elements |
+| **Cinzel** | Fantasy: reserved for themes with a majestic or ancient aesthetic (Crescent, Julia & Jin) |
+
+### Overlay Strategy
+
+The overlay gradient determines what stays visible in the background image.
+
+**Radial (default)** draws attention to the center and darkens edges:
+```css
+--overlay-bg: radial-gradient(circle at center, transparent 0%, var(--bg-primary) 100%);
+```
+
+**Linear** darkens top and bottom and leaves the middle open. Use when the subject
+is horizontally centered and should stay visible (Satisfactory factory floor, SC Sunset horizon):
+```css
+--overlay-bg: linear-gradient(180deg, rgba(R,G,B,0.85) 0%, rgba(R,G,B,0.15) 50%, rgba(R,G,B,0.90) 100%);
+```
+
+Choose based on where the most important part of the image is, not by habit.
+
+---
+
+## Focus & Accessibility
+
+For backgrounds with a lot of detail (many small elements, high contrast, busy textures),
+increase board alpha and blur to reduce visual noise. This makes boards easier to scan,
+especially for users with ADHD or attention sensitivities.
+
+```css
+--bg-board: rgba(R, G, B, 0.65);   /* Up from default 0.55 */
+backdrop-filter: blur(12px);        /* Up from default 8px */
+```
+
+This was applied intentionally to the Satisfactory theme, because the factory floor screenshot
+has a lot going on and needed more visual separation between background and UI.
+
+---
+
+## All 11 Themes
+
+| Theme | File | Accent | Mood | Overlay |
+|---|---|---|---|---|
+| Nebula | `bg-nebula.webp` | `#b359ff` Magenta | Chill, Cosmic | Radial |
+| Crescent | `bg-crescent.webp` | `#d4bd8a` Gold | Luxury, Night | Radial |
+| Event Horizon | `bg-event-horizon.webp` | `#9d5cff` Purple | Deep Space, Void | Radial |
+| Merchantman | `bg-merchantman.webp` | `#2eb8b8` Emerald | Industrial, Alien | Radial |
+| Julia & Jin | `bg-julia-jin.webp` | `#7db3ff` Aetherial Blue | FFXIV Night | Linear |
+| SC Sunset | `bg-sc-sunset.webp` | `#ff8c3d` Amber | Emotional, Horizon | Linear |
+| Hellion HUD | `bg-hellion-hud.webp` | `#32ff6a` Neon Green | Tactical, Admin | Radial |
+| Hellion Energy | `bg-hellion-energy.webp` | `#1eff8e` Acid Green | Overdrive, Power | Radial |
+| Satisfactory | `bg-satisfactory.webp` | `#00b4d8` Cyan | Industrial Desert | Linear |
+| Avorion | `bg-avorion.webp` | `#2ec4a0` Turquoise | Deep Void | Radial |
+| Hellion Stealth | `bg-scPolaris.webp` | `#5ec2ff` Tech Blue | Tactical Recon | Radial |
+
+### Theme Quirks Worth Knowing
+
+**Julia & Jin** uses `Cinzel` as display font and a linear gradient. The subjects in
+the screenshot are positioned left of center, so radial would soften them.
+
+**Satisfactory** has increased board alpha (0.65) and stronger blur (12px), an intentional
+ADHD optimization for a visually busy background.
+
+**Avorion** uses `letter-spacing: 6px` on the logo for maximum HUD feel.
+
+**Hellion Stealth** is the only theme with `border-left: 2px solid var(--accent)` on
+`.bm-item:hover`. Every other theme uses background tinting only. This is intentional
+and gives Stealth its tactical scanner character. Don't apply it to other themes.
+
+---
+
+## Registering a Theme in themes.js
+
+The `THEMES` object in `src/js/themes.js` is the single source of truth for which
+themes exist and which background image they use. CSS handles all the visual variables —
+`themes.js` only needs the image path.
+
+```javascript
+const THEMES = {
+  'nebula':           { bg: 'assets/themes/bg-nebula.webp' },
+  'crescent':         { bg: 'assets/themes/bg-crescent.webp' },
+  'event-horizon':    { bg: 'assets/themes/bg-event-horizon.webp' },
+  'merchantman':      { bg: 'assets/themes/bg-merchantman.webp' },
+  'julia-jin':        { bg: 'assets/themes/bg-julia-jin.webp' },
+  'sc-sunset':        { bg: 'assets/themes/bg-sc-sunset.webp' },
+  'hellion-hud':      { bg: 'assets/themes/bg-hellion-hud.webp' },
+  'hellion-energy':   { bg: 'assets/themes/bg-hellion-energy.webp' },
+  'satisfactory':     { bg: 'assets/themes/bg-satisfactory.webp' },
+  'avorion':          { bg: 'assets/themes/bg-avorion.webp' },
+  'hellion-stealth':  { bg: 'assets/themes/bg-scPolaris.webp' }
+};
+```
+
+To add a new theme, add one line. The key must exactly match the `data-theme`
+attribute in the CSS block. If they don't match, `applyTheme()` will silently
+do nothing and no one will know why.
+
+```javascript
+// New theme: key must match [data-theme="your-theme-name"] in main.css
+'your-theme-name': { bg: 'assets/themes/bg-your-theme.webp' }
+```
+
+### How applyTheme() works
+
+```javascript
+function applyTheme(themeName, skipBgOverride) {
+  const theme = THEMES[themeName];
+  if (!theme) return;
+
+  // Sets data-theme on <html> — activates the matching CSS variable block
+  document.documentElement.setAttribute('data-theme', themeName);
+
+  // Applies the background image unless a custom background is active
+  if (!skipBgOverride) {
+    document.getElementById('bgLayer').style.backgroundImage = `url('${theme.bg}')`;
+  }
+
+  // Updates the active state in the theme picker UI
+  document.querySelectorAll('.theme-card').forEach(card => {
+    card.classList.toggle('active', card.dataset.value === themeName);
+  });
+}
+```
+
+The `skipBgOverride` flag exists for one specific case: when a user has set a custom
+background image, switching themes should still update the CSS variables and the picker
+UI, but not wipe their custom image. Pass `true` to skip the background update.
+
+---
+
+## Adding a Theme Card to newtab.html
+
+The theme picker modal lives in `newtab.html` as `#themeOverlay`. Every theme
+needs a card in the `.theme-grid` — without it the theme exists in CSS and JS
+but never shows up in the UI.
+
+Copy this block and add it inside `.theme-grid`, after the last existing card:
+
+```html
+<div class="theme-card" data-value="your-theme-name">
+  <img class="theme-card-img" src="assets/themes/bg-your-theme.webp" alt="Your Theme" />
+  <span class="theme-card-label">Your Theme</span>
+  <span class="theme-card-check">✓</span>
+</div>
+```
+
+Three things that must match exactly:
+
+- `data-value` must match the key in `THEMES` in `themes.js`
+- `data-value` must match the `[data-theme="..."]` attribute in `main.css`
+- `src` must point to the correct WebP file in `assets/themes/`
+
+The label shown in the picker can be shorter than the full theme name — "HUD" and
+"Energy" are good examples of that. Keep it short enough to fit the card.
+
+The `active` class is toggled by `applyTheme()` automatically, so don't add it
+manually unless you want that theme to be the default on first load (Nebula currently
+has it as fallback).
+
+---
+
+## Adding a New Theme — Checklist

+## Overview
+
+Hellion Dashboard is a browser extension (NewTab replacement) built with **Vanilla JavaScript ES2020**, **CSS Custom Properties**, and **zero dependencies**. No build step, no framework, no bundler — files are loaded directly via `<script>` tags.
+
+**Storage:** `chrome.storage.local` with `localStorage` fallback.
+**Manifest:** V3 across all supported browsers (separate files for Firefox and Opera GX).

+
+## Module Responsibilities
+
+Each module has exactly one responsibility. Communication happens through global references — no import/export, because this is a browser extension without a bundler.
+
+| Module | Responsibility |
+|---|---|
+| `dialog.js` | `HellionDialog.alert()` and `HellionDialog.confirm()` — custom styled dialogs that replace native browser popups. Loaded first so every other module can use it. |
+| `storage.js` | The **only** place that touches `chrome.storage` / `localStorage`. Everything else goes through `Store.get()` / `Store.set()`. |
+| `state.js` | Global `boards` and `settings` arrays, default values, `uid()`, `escHtml()`, `getFaviconUrl()`. |
+| `themes.js` | Applies theme CSS variables. 11 themes, each with its own `[data-theme]` block in `main.css`. |
+| `boards.js` | Renders boards and bookmarks. Event delegation on board containers. |
+| `drag.js` | Board and bookmark reordering via Pointer Events API. |
+| `settings.js` | Settings panel UI, toggle handlers, appearance modal, background upload. |
+| `search.js` | Search bar with engine switching (Google, DuckDuckGo, Bing). |
+| `onboarding.js` | Multi-slide first-run flow including the gaming starter board opt-in. |
+| `widgets.js` | Widget manager — creates DOM, handles drag/resize/z-index, provides registry. See [widget-schema.md](widget-schema.md). |
+| `notes.js` | Notes and checklists as widgets. Multi-instance (max 5). Notebook sidebar. Also handles widget toolbar events. |
+| `calculator.js` | Calculator widget. Single-instance. Shunting-yard expression parser — no `eval()`. |
+| `timer.js` | Timer/countdown widget. Single-instance. Presets, Web Audio API alarm, tab-title blink on completion. |
+| `image-ref.js` | Image reference widget. Multi-instance (max 3). Canvas API WebP conversion, sessionStorage for image data — cleared on browser close. |
+| `data.js` | JSON export/import with validation. Covers boards, notes, calculator history and timer presets. |
+| `app.js` | Entry point. Calls `init()` on DOMContentLoaded. Clock, global event binding. |
+
+---
+
+## Init Sequence
+
+```
+DOMContentLoaded
+  → init()
+    → Store.get('boards')          # Load saved boards
+    → Store.get('settings')        # Load saved settings
+    → applySettings()              # Apply theme, toggles, etc.
+    → renderBoards()               # Render all boards
+    → startClock()                 # Start clock/date display
+    → bindGlobalEvents()           # Header buttons, modals
+    → bindSettingsEvents()         # Settings toggles, theme picker
+    → initSearch()                 # Search bar
+    → migrateSticky()              # Legacy sticky note migration (v1.5.x → v1.6+)
+    → Notes.init()                 # Notes + widget toolbar
+    → Calculator.init()            # Calculator widget
+    → Timer.init()                 # Timer widget
+    → ImageRef.init()              # Image reference widget
+    → initDataButtons()            # Export/import buttons
+    → Onboarding check             # First-run onboarding
+```
+
+---
+
+## Script Load Order
+
+Scripts are loaded in `newtab.html` in dependency order. A module may only reference modules loaded before it — there is no bundler to handle this automatically.
+
+```html
+<script src="src/js/dialog.js"></script>
+<script src="src/js/storage.js"></script>
+<script src="src/js/state.js"></script>
+<script src="src/js/themes.js"></script>
+<script src="src/js/boards.js"></script>
+<script src="src/js/drag.js"></script>
+<script src="src/js/settings.js"></script>
+<script src="src/js/search.js"></script>
+<script src="src/js/onboarding.js"></script>
+<script src="src/js/widgets.js"></script>
+<script src="src/js/notes.js"></script>
+<script src="src/js/calculator.js"></script>
+<script src="src/js/timer.js"></script>
+<script src="src/js/image-ref.js"></script>
+<script src="src/js/data.js"></script>
+<script src="src/js/app.js"></script>
+```
+
+---
+
+## Z-Index Hierarchy
+
+| Layer | z-index | Elements |
+|---|---|---|
+| Background | 0-2 | `#bgLayer`, boards |
+| Search bar | 90 | `.search-bar-wrapper` |
+| Widgets + Toolbar | 100+ | `.widget`, `.widget-toolbar` |
+| Header | 100 | `#header` |
+| Settings panel | 200 | `#settingsPanel` |
+| Dialogs / Modals | 300 | `.hellion-dialog-overlay`, modals |
+| Onboarding | 400 | `#onboardingOverlay` |
+
+Widgets use an incrementing z-index (`WidgetManager._topZ++`) so the last clicked widget always sits on top.
+
+---
+
+## Storage Keys
+
+| Key | Type | Content |
+|---|---|---|
+| `boards` | Array | Board objects with bookmarks |
+| `settings` | Object | User preferences (theme, toggles, etc.) |
+| `widgetStates` | Object | All widget data — see [widget-schema.md](widget-schema.md) |
+| `onboardingDone` | Boolean | Whether the first-run onboarding has been completed |
+| `lastBackupReminder` | Number | Timestamp of the last backup reminder |
+
+---
+
+## Browser Compatibility
+
+| Browser | Engine | Manifest |
+|---|---|---|
+| Chrome | Chromium MV3 | `manifest.json` |
+| Edge | Chromium MV3 | `manifest.json` |
+| Brave | Chromium MV3 | `manifest.json` |
+| Vivaldi | Chromium MV3 | `manifest.json` |
+| Opera / GX | Chromium MV3 | `manifest.opera.json` |
+| Firefox | Gecko MV3 | `manifest.firefox.json` |
+
+Any change that touches manifest fields — version numbers, permissions, content scripts —
+needs to be applied to all three files. The CI quality check will catch it if they drift out of sync.

+# Hellion Dashboard — Code Patterns & Conventions
+

+> is planned for v2.0 — until then, English keeps the docs accessible to anyone
+> who wants to contribute or fork the project.
+
+---
+
+## Core Principles
+
+- **Vanilla JS ES2020** — No frameworks, no TypeScript, no build step
+- **Zero dependencies** — Everything is built from scratch
+- **`createElement` only** — Never use `innerHTML` (XSS prevention)
+- **CSS Custom Properties** — No hardcoded colors, everything through `var(--name)`
+- **Event delegation** — One listener per container, not per element
+- **Storage abstraction** — All storage access through `Store.get()` / `Store.set()`
+
+---
+
+## Pattern: Storage Abstraction
+
+**File:** `src/js/storage.js`
+
+All persistent data goes through the `Store` object. Never access `chrome.storage` or `localStorage` directly — `Store` handles the fallback between the two transparently and provides unified error handling when storage is full.
+
+```javascript
+// Reading
+const boards = await Store.get('boards');    // Returns null if not found
+const settings = await Store.get('settings');
+
+// Writing
+await Store.set('boards', boards);
+await Store.set('settings', settings);
+
+// Quota check (chrome.storage only, 10 MB limit)
+await Store.checkQuota();
+```
+
+---
+
+## Pattern: Event Delegation
+
+One listener on the container, `closest()` to find the target. Much cleaner than attaching a listener to every single element, and it works automatically for dynamically added content.
+
+```javascript
+// GOOD — one listener, handles all bookmarks
+container.addEventListener('click', (e) => {
+  const bmItem = e.target.closest('.bm-item');
+  if (!bmItem) return;
+  const id = bmItem.dataset.id;
+  // Handle click
+});
+
+// BAD — listener per element
+bookmarks.forEach(bm => {
+  bm.addEventListener('click', handler);  // Don't do this!
+});
+```
+
+Used in `boards.js` (board/bookmark events), `notes.js` (toolbar) and `calculator.js` (button grid).
+
+---
+
+## Pattern: createElement over innerHTML
+
+Always build DOM with `document.createElement()`. This is the project's #1 security rule — `innerHTML` with user-provided content is an XSS risk, full stop.
+
+```javascript
+// GOOD
+const link = document.createElement('a');
+link.href = bookmark.url;
+link.textContent = bookmark.title;
+container.appendChild(link);
+
+// BAD — XSS risk!
+container.innerHTML = `<a href="${url}">${title}</a>`;
+```
+
+---
+
+## Pattern: Shared Storage Key
+
+All widget modules share the `widgetStates` storage key. Every module that writes to it must read first and preserve what's already there — otherwise modules silently overwrite each other's data.
+
+```javascript
+async save() {
+  const data = await Store.get('widgetStates') || {};
+
+  // Write your own data
+  data.yourKey = { /* ... */ };
+
+  // Don't replace the whole object — other modules live here too
+  await Store.set('widgetStates', data);
+}
+```
+
+See [widget-schema.md](widget-schema.md) for the full `widgetStates` structure.
+
+---
+
+## Pattern: Widget Lifecycle Hooks
+
+Single-instance widgets (Calculator, Timer) need to react when they're closed, minimized, or reopened. They do this by wrapping `WidgetManager` methods in their `init()`.
+
+```javascript
+async init() {
+  const prevClose = WidgetManager.close;
+  const self = this;
+
+  WidgetManager.close = function(id) {
+    prevClose.call(WidgetManager, id);
+    if (id === self.WIDGET_ID) {
+      self.onClose();
+    }
+  };
+
+  const prevMinimize = WidgetManager.minimize;
+  WidgetManager.minimize = async function(id) {
+    await prevMinimize.call(WidgetManager, id);
+    if (id === self.WIDGET_ID) {
+      self._isOpen = false;
+      await self.save();
+    }
+  };
+}
+```
+
+Multiple widgets chain these wraps — Calculator wraps first, Timer wraps Calculator's already-wrapped version, and so on. Always call the previous method (`prevClose.call(...)`) or the chain breaks and other widgets stop responding.
+
+---
+
+## Pattern: Debounced Save
+
+For frequent updates like typing in notes or dragging widgets, debouncing avoids hammering storage with a write on every keystroke.
+
+```javascript
+_saveTimer: null,
+
+_debouncedSave() {
+  clearTimeout(this._saveTimer);
+  this._saveTimer = setTimeout(() => this.save(), 500);
+}
+
+// Use _debouncedSave() instead of save() for frequent events
+textarea.addEventListener('input', () => {
+  noteData.content = textarea.value;
+  this._debouncedSave();
+});
+```
+
+Used in `notes.js` (text editing) and `image-ref.js` (label editing).
+
+---
+
+## Pattern: Theme System
+
+All themes use CSS Custom Properties in `[data-theme="name"]` blocks in `main.css`. There are currently 11 themes.
+
+```css
+[data-theme="nebula"] {
+  --bg-primary: #0a0e17;
+  --bg-board: rgba(15, 20, 35, 0.65);
+  --text-primary: #e0e6f0;
+  --accent: #7db3ff;
+  --border: rgba(125, 179, 255, 0.12);
+  /* ... more variables */
+}
+```
+
+Never hardcode colors in JS. Let CSS handle it.
+
+```javascript
+// GOOD
+element.classList.add('active');
+
+// BAD — breaks every theme that isn't Nebula
+element.style.color = '#7db3ff';
+```
+
+---
+
+## Pattern: Onboarding Slides
+
+The onboarding system in `onboarding.js` is data-driven. Each slide is a plain object — add a new slide by adding an object to the `slides` array, the `_render()` method handles the rest.
+
+```javascript
+{
+  hero: '🎮',                    // Large emoji/icon
+  title: 'Slide Title',
+  text: 'Optional description',
+  features: ['Item 1', ...],     // Optional bullet list
+  showThemes: true,              // Optional theme grid
+  interactive: 'gaming-board'    // Optional custom buttons
+}
+```
+
+---
+
+## Pattern: Dialog System
+
+Custom dialogs replace native `alert()` and `confirm()` everywhere in the project.
+
+```javascript
+// Informational
+await HellionDialog.alert('Message text', {
+  type: 'info',   // 'info', 'success', 'warning', 'danger'
+  title: 'Title'
+});
+
+// Yes/no
+const ok = await HellionDialog.confirm('Are you sure?', {
+  type: 'danger',
+  title: 'Delete',
+  confirmText: 'Delete',
+  cancelText: 'Cancel'
+});
+if (ok) { /* user confirmed */ }
+```
+
+---
+
+## Pattern: Pointer Events for Drag
+
+Widget dragging and board reordering use the Pointer Events API instead of mouse events. The reason: Pointer Events work with both mouse and touch, and `setPointerCapture` keeps the events flowing even if the cursor leaves the element mid-drag.
+
+```javascript
+element.addEventListener('pointerdown', (e) => {
+  element.setPointerCapture(e.pointerId);
+
+  function onMove(ev) {
+    // Update position
+  }
+
+  function onUp() {
+    element.releasePointerCapture(e.pointerId);
+    element.removeEventListener('pointermove', onMove);
+    element.removeEventListener('pointerup', onUp);
+  }
+
+  element.addEventListener('pointermove', onMove);
+  element.addEventListener('pointerup', onUp);
+});
+```
+
+---
+
+## Pattern: Canvas API Image Processing
+
+The image reference widget converts uploaded images to WebP locally in the browser — no external service, no upload, nothing leaves the device.
+
+```javascript
+_processFile(file) {
+  return new Promise((resolve, reject) => {
+    const objectUrl = URL.createObjectURL(file);
+    const img = new Image();
+
+    img.onload = () => {
+      const canvas = document.createElement('canvas');
+      canvas.width = img.width;
+      canvas.height = img.height;
+      const ctx = canvas.getContext('2d');
+      ctx.drawImage(img, 0, 0);
+      const webpUrl = canvas.toDataURL('image/webp', 0.85);
+      URL.revokeObjectURL(objectUrl);   // Always free the object URL
+      resolve(webpUrl);
+    };
+
+    img.onerror = () => {
+      URL.revokeObjectURL(objectUrl);
+      reject(new Error('Image could not be loaded'));
+    };
+
+    img.src = objectUrl;
+  });
+}
+```
+
+Always call `URL.revokeObjectURL()` after the image has loaded — skipping it leaks memory.
+
+---
+
+## Coding Rules Summary
+
+| Rule | Rationale |
+|---|---|
+| `createElement` only, never `innerHTML` | XSS prevention |
+| All storage through `Store` | Browser compatibility + unified error handling |
+| CSS variables, no hardcoded colors | Theme support across all 11 themes |
+| Event delegation | Performance, works with dynamic content |
+| `const`/`let`, never `var` | Block scoping |
+| No external dependencies | Extension simplicity |
+| No build step | Direct development, no toolchain to break |
+| JSDoc comments on public functions | Documentation for contributors |
+| URL validation before `href` | Security |
+| Error handling on storage operations | Graceful failure |
+| `URL.revokeObjectURL()` after Canvas ops | Memory management |
+
+---
+
+## Manifest Synchronization
+
+Three manifest files must always stay in sync:
+
+- `manifest.json` — Chrome, Edge, Brave, Vivaldi
+- `manifest.firefox.json` — Firefox
+- `manifest.opera.json` — Opera, Opera GX
+
+Version numbers, permissions and content script entries need to be updated in all three. The CI quality check will catch drift, but it's cleaner not to let it get there in the first place.

+
+## Overview
+
+The widget system provides draggable, resizable floating panels managed by `WidgetManager` (`src/js/widgets.js`). Each widget type has its own module that handles content rendering and state management — `WidgetManager` only knows about DOM and position, never about content.
+
+---
+
+## Widget Types
+
+| Type | Module | Instance | Max | Storage |
+|---|---|---|---|---|
+| `note` | `notes.js` | Multi | 5 | Persistent (`widgetStates.notes`) |
+| `calculator` | `calculator.js` | Single | 1 | Persistent (`widgetStates.calculator`) |
+| `timer` | `timer.js` | Single | 1 | Persistent (`widgetStates.timer`) |
+| `image` | `image-ref.js` | Multi | 3 | Meta: persistent, Image data: sessionStorage |
+
+---
+
+## WidgetManager API
+
+### `create(type, config) → string`
+
+Creates a widget and appends it to the DOM. Returns the widget ID.
+
+```javascript
+const id = WidgetManager.create('note', {
+  id: 'note_abc123',  // Optional, auto-generated if omitted
+  title: 'My Note',  // Default: 'Note'
+  x: 120,            // Left position in px
+  y: 80,             // Top position in px
+  width: 280,        // Width in px (min: 200)
+  height: 220,       // Height in px (min: 150)
+  open: true         // Visible state (default: true)
+});
+```
+
+### `getBody(id) → HTMLElement | null`
+
+Returns the `.widget-body` element. This is where your module renders its content.
+
+```javascript
+const body = WidgetManager.getBody('widget_calculator');
+if (body) Calculator.renderBody(body);
+```
+
+### `getState(id) → Object | null`
+
+Returns the current widget state — position, size, open status.
+
+```javascript
+const state = WidgetManager.getState('widget_timer');
+// → { id, type, title, x, y, width, height, open }
+```
+
+### `close(id)`
+
+Permanently removes a widget from the DOM and registry. No undo.
+
+### `minimize(id)`
+
+Hides a widget with animation. The widget stays in the registry with `open: false` so it can be restored.
+
+### `openWidget(id)`
+
+Restores a minimized widget with animation.
+
+### `bringToFront(id)`
+
+Increments z-index so the widget sits above everything else. Called automatically on `pointerdown`.
+
+### `save() → Array`
+
+Returns an array of all `type: 'note'` widget states. Used by `Notes.save()` to merge position/size data with note content.
+
+### `restore(renderCallback)`
+
+Loads widget states from storage and recreates all note widgets. Single-instance widgets (Calculator, Timer) restore themselves in their own `init()` — `restore()` only handles notes.
+
+---
+
+## Shared Storage Key: `widgetStates`
+
+All widget modules share a single storage key. Every module's `save()` must read first and preserve whatever it doesn't own — otherwise modules silently wipe each other's data on every save.
+
+```javascript
+// Full widgetStates structure
+{
+  notes: [
+    {
+      id: 'note_abc123',
+      title: 'My Note',
+      content: 'Hello world',
+      template: 'text',      // 'text' or 'checklist'
+      x: 120, y: 80,
+      width: 280, height: 220,
+      open: true,
+      checklistItems: [],    // Only used by checklist template
+      checkedItems: []       // Checked item IDs
+    }
+  ],
+  calculator: {
+    x: 400, y: 120,
+    width: 280, height: 400,
+    open: false,
+    history: [
+      { expr: '2 + 3', result: '5' }
+    ]
+  },
+  timer: {
+    x: 600, y: 80,
+    width: 260, height: 360,
+    open: false,
+    muted: false,
+    presets: [
+      { name: 'Forschung', seconds: 2700 }
+    ]
+  },
+  imageRef: {
+    images: [
+      {
+        id: 'image_0',
+        label: 'Bauplan',
+        x: 200, y: 120,
+        width: 320, height: 280,
+        open: true
+        // Image data is NOT stored here — sessionStorage only
+      }
+    ]
+  }
+}
+```
+
+### The Save Pattern
+
+Every module that touches `widgetStates` must follow this pattern:
+
+```javascript
+// From notes.js — same pattern applies to every widget module
+async save() {
+  const existing = await Store.get(this.STORAGE_KEY);
+  const saveData = { notes: mergedNotes };
+
+  // Preserve everything we don't own
+  if (existing && existing.calculator) saveData.calculator = existing.calculator;
+  if (existing && existing.timer)      saveData.timer      = existing.timer;
+  if (existing && existing.imageRef)   saveData.imageRef   = existing.imageRef;
+
+  await Store.set(this.STORAGE_KEY, saveData);
+}
+```
+
+---
+
+## Creating a New Widget Type
+
+### Step 1: Single or Multi-Instance?
+
+**Single-instance** (Calculator, Timer style): one widget, fixed ID, `toggle()` opens and closes it.
+**Multi-instance** (Notes, ImageRef style): multiple widgets, dynamic IDs, `create()` adds new ones.
+
+### Step 2: Create the Module
+
+Here's a minimal single-instance widget template. Follow the same structure — the lifecycle hooks especially are easy to get wrong.
+
+```javascript
+const YourWidget = {
+  WIDGET_ID: 'widget_yourwidget',
+  STORAGE_KEY: 'widgetStates',
+  _isOpen: false,
+
+  async load() {
+    const data = await Store.get(this.STORAGE_KEY);
+    if (data && data.yourWidget) {
+      // Restore your state
+    }
+  },
+
+  async save() {
+    const data = await Store.get(this.STORAGE_KEY) || {};
+    if (data.notes === undefined) data.notes = [];
+
+    const widgetState = WidgetManager.getState(this.WIDGET_ID);
+    data.yourWidget = {
+      x:      widgetState ? widgetState.x      : 400,
+      y:      widgetState ? widgetState.y      : 120,
+      width:  widgetState ? widgetState.width  : 280,
+      height: widgetState ? widgetState.height : 300,
+      open:   this._isOpen,
+      // ... your custom data
+    };
+
+    await Store.set(this.STORAGE_KEY, data);
+  },
+
+  async open() {
+    if (this._isOpen) {
+      WidgetManager.bringToFront(this.WIDGET_ID);
+      return;
+    }
+
+    const data = await Store.get(this.STORAGE_KEY);
+    const saved = (data && data.yourWidget) ? data.yourWidget : {};
+
+    WidgetManager.create('yourwidget', {
+      id:     this.WIDGET_ID,
+      title:  'Your Widget',
+      x:      saved.x      || 400,
+      y:      saved.y      || 120,
+      width:  saved.width  || 280,
+      height: saved.height || 300,
+      open:   true
+    });
+
+    const body = WidgetManager.getBody(this.WIDGET_ID);
+    if (body) this.renderBody(body);
+
+    this._isOpen = true;
+    await this.save();
+  },
+
+  async toggle() {
+    if (this._isOpen) {
+      const entry = WidgetManager._widgets.get(this.WIDGET_ID);
+      if (entry && entry.state.open) {
+        await WidgetManager.minimize(this.WIDGET_ID);
+        this._isOpen = false;
+        await this.save();

+
+### Step 3: Integration Checklist
+
+1. `newtab.html` — Add `<script>` tag after `widgets.js` and before `data.js`
+2. `newtab.html` — Add toolbar button: `<button class="widget-toolbar-btn" data-action="your-action">`
+3. `notes.js` — Add handler in `initToolbar()`: `else if (action === 'your-action') { YourWidget.toggle(); }`
+4. `notes.js` — Preserve your key in `save()`: `if (existing && existing.yourWidget) saveData.yourWidget = existing.yourWidget;`
+5. `app.js` — Add `await YourWidget.init();` to the init sequence
+6. `main.css` — Add widget-specific styles
+7. `data.js` — Add export/import logic if your data should survive a JSON backup
+
+---
+
+## Widget DOM Structure
+
+Every widget created by `WidgetManager.create()` has this structure. Your module renders into `.widget-body` via `renderBody()` — never touch the header or resize handle.
+
+```html
+<div class="widget" data-widget-id="widget_abc123"
+     style="left: 120px; top: 80px; width: 280px; height: 220px;">
+  <div class="widget-header">         <!-- Drag handle -->
+    <span class="widget-title">Title</span>   <!-- Double-click to edit, max 20 chars -->
+    <div class="widget-actions">
+      <button class="widget-btn widget-minimize">─</button>
+      <button class="widget-btn widget-close">✕</button>
+    </div>
+  </div>
+  <div class="widget-body">
+    <!-- Your content goes here via renderBody() -->
+  </div>
+  <div class="widget-resize-handle"></div>   <!-- Bottom-right, visible on hover -->
+</div>
+```

+# ⬡ Opera GX — New-Tab Workaround
+
+Opera GX ist der einzige Browser in diesem Projekt der sich aktiv dagegen wehrt,
+eine eigene New-Tab-Seite zu nutzen. Während Chrome, Edge, Firefox und selbst Vivaldi
+einfach `chrome_url_overrides` respektieren, priorisiert Opera GX seine eigene
+Speed Dial Seite und ignoriert den Standard-Override für entpackte Erweiterungen.
+
+Das Ergebnis: vier Stunden Debugging, zwei Workaround-Skripte und ein Reddit-Thread
+der tatsächlich geholfen hat. Hier ist was dabei rausgekommen ist.
+
+---
+
+## Warum zwei extra Skripte?
+
+| Browser | New-Tab Override | Zusatzaufwand |
+|---|---|---|
+| Chrome / Edge / Brave / Vivaldi | `chrome_url_overrides` | Keiner |
+| Firefox | `chrome_url_overrides` (MV3) | Eigenes Manifest |
+| Opera / Opera GX | Blockiert durch Speed Dial | Dieser Ordner hier |
+
+---
+
+## Was passiert hier?
+
+### `background.js` — Tab-Management
+
+Überwacht Tab-Aktivitäten im Hintergrund und greift ein bevor Opera seine Startseite laden kann.
+
+- Erkennt `opera://startpage/` und `chrome://startpage/`
+- Leitet per `chrome.tabs.update` auf `newtab.html` um
+- Prüft zusätzlich bei `onActivated`, weil Opera manche Tabs im Hintergrund lädt
+  und der erste Redirect dann nicht greift
+
+### `redirect.js` — In-Page Redirect
+
+Manche Opera-Systemprozesse sind so weit isoliert dass ein externer Eingriff
+nicht zuverlässig ankommt. Also nochmal von innen.
+
+- Wird als Content Script direkt in Opera-Startseiten-Bereiche injiziert
+- Löst den Redirect bei `document_start` aus, bevor die Speed Dial Seite
+  überhaupt anfangen kann sich aufzubauen
+
+Ja, es braucht wirklich beide Skripte. Opera GX hat das so entschieden.
+
+Das Gute daran: die GitHub Actions kümmern sich darum dass jeder Browser nur bekommt
+was er braucht. Das Opera-ZIP enthält die Workaround-Skripte, das Chrome-ZIP nicht.
+Wer sich das manuell zusammensuchen müsste wäre vermutlich genauso genervt wie ich
+beim Debuggen war.
+
+---
+
+## Datenschutz
+
+Kein Tracking, keine Speicherung, keine externen Requests.
+Nur Standard-Browser-APIs, `chrome.tabs`, um zurückzubekommen was eigentlich
+standardmäßig funktionieren sollte.
+
+**100% lokal. 0% Analytics. Wie im gesamten Hellion NewTab Projekt.**
