merge: v1.1.0 Theme Foundation

First major UI cycle after the standalone v1.0.0 cut. Theme engine
with five built-in themes (Hellion Arctic, Chat 2 Klassik, Event
Horizon, Moonlit Bloom, Mint Grove), customisable JSON themes,
modernised settings layout (card-grid overview + breadcrumb detail
view), opt-in per-theme chat-channel colours, and the plugin icon
swap to the Hellion Forge hammer.

Configuration v13 → v14: all users land on Hellion Arctic. Pick
Chat 2 Klassik in Settings → Themes for the upstream look.

See HellionChat/HellionChat.yaml changelog and docs/CHANGELOG.md for
the full release notes; docs/THEME-AUTHORING.md is the new guide for
writing custom themes.

 changelog: |-
+  **Hellion Chat 1.1.0 — Theme Foundation**
+
+  First major UI cycle after the standalone v1.0.0 cut. Theme engine,
+  five built-in themes, customisable JSON themes, modernised settings
+  layout.
+
+  New themes (Settings → Themes):
+
+  - **Hellion Arctic** — the brand default, Arctic Cyan + Ember Glow
+    on industrial slate.
+  - **Chat 2 Klassik** — Steel Blue on neutral grey, eckige Kanten.
+    The upstream Chat 2 look on the new engine.
+  - **Event Horizon** — Cosmic Purple on near-black. Deep-space mood.
+  - **Moonlit Bloom** — Bloom Magenta + Soft Sage on deep-violet
+    night.
+  - **Mint Grove** — Mint Green + Honey Amber on deep forest. First
+    member of the Grove family.
+
+  Theme engine highlights:
+
+  - Slug-based selection in Settings → Themes with mini-mockup
+    previews per theme.
+  - Click a theme card and the whole plugin (chat, settings,
+    pop-outs, viewer) repaints instantly.
+  - Custom themes via JSON in pluginConfigs/HellionChat/themes/.
+    Example template seeded on first launch.
+  - Optional per-theme chat-channel colours. When a theme proposes
+    its own chat colours and yours differ, a dezent banner offers
+    Apply / Keep — never auto-overwriting.
+  - Migration v13 → v14: existing users land on Hellion Arctic. Pick
+    Chat 2 Klassik to keep the upstream look.
+
+  Settings layout:
+
+  - New card-grid overview on Settings open. Click a card to drill
+    into the section.
+  - Breadcrumb back to overview, ESC also returns.
+  - Detail view drops the redundant tab list — section content uses
+    the full width.
+
+  Branding:
+
+  - Plugin icon swapped from the ChatTwo derivative to the Hellion
+    Forge hammer.
+  - New docs/THEME-AUTHORING.md walks you through writing your own
+    themes with the Forge logo on top.
+
+  Technical:
+
+  - HellionStyle.PushGlobal is now theme-driven. Configuration.
+    HellionThemeEnabled is deprecated and will be removed in v1.2.0.
+  - New ThemeRegistry singleton with LastWriteTime-cached custom-
+    theme loader.
+  - 51 local unit tests cover the data model, registry, JSON round-
+    trip and built-in sanity checks.
+
+  Based on Chat 2 1.35.3 (upstream Infiziert90/ChatTwo, EUPL-1.2).

+# Theme Authoring Guide
+
+> Built by **Hellion Forge** — the plugin workshop arm of [Hellion Online Media](https://hellion-media.de). HellionChat ships with five built-in themes; this guide walks you through writing your own.
+
+## TL;DR
+
+1. Open Settings → Themes → **Open themes folder**
+2. Copy `example-theme.json` to `<your-name>.json` in the same folder
+3. Edit the file with any text editor
+4. Reload the plugin (toggle off/on in `/xlplugins`)
+5. Your theme appears in the Custom-Themes section in Settings → Themes
+
+That's the whole loop. The rest of this document is reference.
+
+## File location
+
+```
+%APPDATA%\XIVLauncher\pluginConfigs\HellionChat\themes\
+```
+
+(or the equivalent path on Linux/macOS — Settings → Themes → "Open themes folder" opens it directly).
+
+Each `*.json` file in this folder is loaded as one theme. The `example-theme.json` that HellionChat seeds on first launch is your starting template.
+
+## File format
+
+Theme JSON has four blocks:
+
+```json
+{
+  "schemaVersion": 1,
+  "slug": "your-slug",
+  "name": "Your Theme Name",
+  "author": "You",
+  "description": "One-line description shown under the theme name.",
+  "colors":   { ... 21 color slots ... },
+  "layout":   { ...  9 layout values ... },
+  "chatChannels": { ... optional, channel-name → hex ... }
+}
+```
+
+### Top-level fields
+
+| Field | Type | Required | Notes |
+|---|---|---|---|
+| `schemaVersion` | int | yes | Always `1` for HellionChat 1.1.0. The plugin warns and skips themes with a different number. |
+| `slug` | string | yes | Lowercase, hyphenated. Must be unique across all themes (built-in slugs are reserved). |
+| `name` | string | yes | Display name in the picker. |
+| `author` | string | yes | Shown small under the theme name. |
+| `description` | string | yes | One short sentence. |
+| `colors` | object | yes | All 21 slots required (see below). |
+| `layout` | object | yes | All 9 slots required (see below). |
+| `chatChannels` | object | no | Optional channel-name → hex map (see below). |
+
+### Color slots
+
+All values are 6-digit `#RRGGBB` or 8-digit `#RRGGBBAA` hex strings. Six-digit values get an implicit `FF` alpha.
+
+| Slot | Role |
+|---|---|
+| `primary` | Brand color — used on buttons, sliders, check marks, highlighted separators. |
+| `primaryDark` | Pressed-button stage. |
+| `primaryLight` | Hovered-button / link-text stage. |
+| `primaryGlow` | Glow / subtle accent (typically primary with ~60% alpha). |
+| `accent` | Counter-accent — scrollbar grab on hover/active, resize grip, optional CTA. |
+| `accentDark` / `accentLight` | Dark/light siblings of accent. |
+| `identity` | Title-bar active color and active-tab color. Often equals `primaryDark`. |
+| `windowBg` | Outermost window background. |
+| `childBg` | Inner panel / popup background. |
+| `frameBg` | Input fields, sliders, combos. |
+| `surface` | Card surfaces, headers, selectables. |
+| `surfaceHover` | Hovered card / header step. |
+| `border` | Panel borders. Typically primary with ~40% alpha for a brand-tinted edge. |
+| `textPrimary` | Body text. Soft off-white reads better than pure `#FFFFFF` on dark backgrounds. |
+| `textMuted` | Captions, secondary lines. |
+| `textDim` | Disabled / hint text, separators. |
+| `statusSuccess` | Green-ish for success notifications. |
+| `statusDanger` | Red for errors. |
+| `statusWarning` | Amber for warnings. |
+| `statusInfo` | Cyan-ish info. Often equals primary. |
+
+### Layout slots
+
+All values are floats in pixels. `BorderSize` is 0 or 1 (no thicker borders look right with ImGui's edge anti-aliasing).
+
+| Slot | Typical range | Notes |
+|---|---|---|
+| `windowRounding` | 0–8 | 0 = sharp upstream look; 4–6 = softer "app" feel. |
+| `childRounding` | 0–6 | Usually 1 less than `windowRounding`. |
+| `popupRounding` | 0–6 | Same as `childRounding`. |
+| `frameRounding` | 0–4 | For inputs, sliders. |
+| `grabRounding` | 0–4 | Slider grab dot. |
+| `tabRounding` | 0–4 | Tab corners. |
+| `scrollbarRounding` | 0–4 | Scrollbar grab. |
+| `windowBorderSize` | 0 or 1 | 1 reads better in dark themes. |
+| `frameBorderSize` | 0 or 1 | Usually matches windowBorderSize. |
+
+### Optional `chatChannels`
+
+If present, your theme proposes its own chat-channel colors. Property names are `ChatType` enum values (case-insensitive). Unknown names are skipped silently — safe for forward-compat.
+
+```json
+"chatChannels": {
+  "Say":             "#FFFFFF",
+  "Yell":            "#FFE066",
+  "Shout":           "#FFA040",
+  "TellIncoming":    "#FF99CC",
+  "TellOutgoing":    "#FF99CC",
+  "Party":           "#80C0E8",
+  "FreeCompany":     "#4DD9E8",
+  "NoviceNetwork":   "#A8E060",
+  "Linkshell1":      "#A8E060"
+}
+```
+
+The user is asked **once per theme switch** whether to apply these colors — never auto-overwriting existing picks. The banner shows up only if your suggested colors differ from the user's current `Configuration.ChatColours`.
+
+#### Channel-identity rule
+
+**Don't break FFXIV channel identity.** Players have used these conventions for over a decade:
+
+| Channel | Convention | Why |
+|---|---|---|
+| Say | white / off-white | Default-readable speech. |
+| Yell | yellow | Urgent broadcast. |
+| Shout | orange | Local urgent. |
+| Tell | pink-magenta | Whisper, must stand out. |
+| Party | light blue | Group ops. |
+| FreeCompany | cyan-teal | Guild ops. |
+| NoviceNetwork | lime-green | Mentor channel. |
+
+A theme can tint these toward its brand family (e.g., a purple theme can shift Tell from `#FF99CC` to `#E090FF`), but **don't** flip them (Tell suddenly green, Yell suddenly cyan). RP groups and combat-spec setups depend on the visual hierarchy.
+
+The four colored built-in themes (Hellion Arctic, Event Horizon, Moonlit Bloom, Mint Grove) all follow this rule — read their JSON for reference. Chat 2 Klassik intentionally ships without `chatChannels` so the user keeps their existing picks.
+
+## Theme families
+
+Naming convention `<color>-<modifier>` is recommended for theme families. The first member of a family is the lightest/brightest:
+
+- `mint-grove` (current built-in, light mint)
+- `forest-grove` (planned, dark emerald)
+- `moss-grove` (planned, mid muted)
+
+Code-wise families have no special handling — only the slug naming hints at the relationship. The picker may group families later, but that's not required.
+
+## Validation and errors
+
+When HellionChat loads your theme:
+
+- **Schema mismatch** (`schemaVersion != 1`): theme is skipped, warning written to `/xllog`.
+- **Missing required field** (e.g., no `slug`): theme is skipped, warning written.
+- **Invalid hex** (e.g., `#GGHHII`): theme is skipped, warning written.
+- **Unknown channel name** in `chatChannels`: that one channel is skipped silently, the rest of the theme loads normally.
+
+Check `/xllog` after a plugin reload to see what loaded and what didn't.
+
+## Testing your theme
+
+1. Edit the JSON, save the file.
+2. Reload the plugin: `/xlplugins` → toggle HellionChat off, then on.
+3. Settings → Themes → click your theme card.
+4. Watch every plugin window (chat, settings, pop-out) and pick something to fix.
+5. Tweak. Reload. Repeat.
+
+Tip: the **Settings → Themes** picker shows a mini-mockup per theme — your colors are visible before you switch.
+
+## Sharing themes
+
+Themes are JSON, so sharing is just a file. Drop it into someone's `pluginConfigs/HellionChat/themes/` folder and their plugin picks it up on next reload.
+
+A community theme repository is on the Hellion Forge roadmap. Until then: share via Discord or any pastebin.
+
+## Reference
+
+- `docs/example-theme.json` (seeded automatically on first launch into `pluginConfigs/HellionChat/themes/`) — minimal valid theme.
+- The five built-in themes live in source under `HellionChat/Themes/Builtin/`. They are a good reference for Color choices that work.
+- [Hellion Online Media branding](https://hellion-media.de) — the Arctic Cyan + Ember Glow palette that drives the default Hellion Arctic theme.
