 ## Browser-Kompatibilität

-| Chrome | Kompatibel | V3 (`manifest.json`) |
-| Edge | Kompatibel | V3 (`manifest.json`) |
-| Brave | Kompatibel | V3 (`manifest.json`) |
-| Opera | Kompatibel | V3 (`manifest.json`) |
-| Opera GX | Kompatibel | V3 (`manifest.json`) |
-| Vivaldi | Kompatibel | V3 (`manifest.json`) |
-| Firefox | Kompatibel | V2 (`manifest.firefox.json`) |
+|---|---|---|
+| Chrome | ✅ Kompatibel | V3 (`manifest.json`) |
+| Edge | ✅ Kompatibel | V3 (`manifest.json`) |
+| Brave | ✅ Kompatibel | V3 (`manifest.json`) |
+| Opera | ✅ Kompatibel | V3 (`manifest.opera.json`) |
+| Opera GX | ✅ Kompatibel | V3 (`manifest.opera.json`) |
+| Vivaldi | ✅ Kompatibel | V3 (`manifest.json`) |
+| Firefox | ✅ Kompatibel | V3 (`manifest.firefox.json`) |

-> **Firefox-Hinweis:** Firefox verwendet aktuell Manifest V2. Mozilla arbeitet an MV3-Support —
-> sobald stabil, wird die Extension migriert. MV2 wird von Mozilla weiterhin unterstützt.
+> **Firefox-Hinweis:** Ab v1.2.0 läuft die Extension auf Manifest V3 — identisch zu Chrome/Edge.
+> `manifest.firefox.json` bleibt als separate Datei erhalten für Firefox-spezifische Anpassungen.

+# ⬡ Hellion Dashboard — Design & Theme-System
+
+Leitfaden für das visuelle Design des Hellion Dashboards. Definiert wie Themes aufgebaut
+sind und welche Patterns konsistent eingehalten werden — für eine immersive, fokussierte
+Nutzererfahrung.
+
+---
+
+## Design-Säulen
+
+| Säule | Beschreibung |
+|---|---|
+| **Immersion** | Das Interface wirkt wie ein HUD das über der Szenerie schwebt — kein Fremdkörper |
+| **Visual Clarity** | Gezielter `blur`-Einsatz trennt UI und Hintergrundbild — reduziert Reizüberflutung |
+| **Harmonie** | Jedes Theme zieht seine Farben aus den dominanten Lichtquellen des Hintergrundbildes |
+
+---
+
+## Anatomie eines Themes
+
+Jedes Theme folgt dieser Variablen-Struktur in `main.css`.
+Für ein neues Theme diesen Block kopieren und anpassen:
+
+```css
+[data-theme="dein-theme-name"] {
+  /* 1. AKZENTE — Die Lichtquelle */
+  --accent:          #HEXCODE;             /* Hauptfarbe (Neon/Licht) */
+  --accent-dim:      rgba(R, G, B, 0.12);  /* Subtiler Hintergrund */
+  --accent-glow:     rgba(R, G, B, 0.08);  /* Glow für Logo & Uhr */
+  --border-accent:   rgba(R, G, B, 0.25);  /* Fokus-Rahmen */
+
+  /* 2. BASIS — Das Fundament */
+  --bg-primary:      #HEXCODE;             /* Dunkelster Punkt im Bild */
+  --bg-board:        rgba(R, G, B, 0.55);  /* Glas-Effekt der Boards */
+
+  /* 3. TEXT — Kontrast */
+  --text-primary:    #FFFFFF;              /* Klar lesbar, leicht getönt */
+  --text-secondary:  #A0A0A0;             /* Entsättigt für weniger Rauschen */
+
+  /* 4. OVERLAY — Vignette */
+  --overlay-bg: radial-gradient(
+    circle at center,
+    transparent 0%,
+    var(--bg-primary) 100%
+  );
+}
+```
+
+---
+
+## UI-Patterns
+
+### Frosted Glass
+
+Hardware-beschleunigter Blur für Lesbarkeit auf komplexen Hintergründen:
+
+```css
+backdrop-filter: blur(8px);
+```
+
+Erzeugt Tiefe und visuelle Ruhe hinter Text und UI-Elementen.
+
+### Typografie-Hierarchie
+
+| Font | Einsatz |
+|---|---|
+| **Rajdhani** | Display — Uhr, Titel, Logo. Alles was nach "System" aussieht |
+| **Inter** | Body — Bookmark-Titel, Listen, interaktive Elemente |
+| **Cinzel** | Fantasy — Exklusiv für Themes mit majestätischem oder antikem Vibe (Crescent, Julia & Jin) |
+
+---
+
+## Theme-Übersicht
+
+| Theme | Akzentfarbe | Stimmung |
+|---|---|---|
+| Nebula | `#b359ff` Magenta | Chill, Cosmic |
+| Crescent | `#d4bd8a` Gold | Luxury, Night |
+| Event Horizon | `#9d5cff` Purple | Deep Space, Void |
+| Merchantman | `#2eb8b8` Emerald | Industrial, Alien |
+| Julia & Jin | `#7db3ff` Aetherial Blue | FFXIV Night |
+| SC Sunset | `#ff8c3d` Amber | Emotional, Horizon |
+| Hellion HUD | `#32ff6a` Neon Green | Tactical, Admin |
+| Hellion Energy | `#1eff8e` Acid Green | Overdrive, Power |
+
+---
+
+## ADHS-Optimierung
+
+Bei Hintergrundbildern mit vielen Details (z.B. Julia & Jin) den Board-Alpha erhöhen
+und den Blur verstärken — das dimmt das Hintergrundrauschen und lässt das Gehirn
+schneller die relevanten Informationen erfassen:
+
+```css
+--bg-board: rgba(R, G, B, 0.65);
+backdrop-filter: blur(12px);
+```

+# ⬡ Opera GX — New-Tab Workaround
+
+Opera GX priorisiert die eigene Speed Dial Seite und ignoriert `chrome_url_overrides`
+für entpackte Erweiterungen. Um das Hellion Dashboard trotzdem als New-Tab-Seite
+zu etablieren, kommen zwei zusätzliche Skripte zum Einsatz.
+
+---
+
+## Warum zwei extra Skripte?
+
+| Browser | New-Tab Override | Zusatzaufwand |
+|---|---|---|
+| Chrome / Edge / Brave / Vivaldi | `chrome_url_overrides` | Keiner |
+| Firefox | `chrome_url_overrides` (MV2) | Eigenes Manifest |
+| Opera / Opera GX | Blockiert durch Speed Dial | Workaround nötig |
+
+---
+
+## Was passiert hier?
+
+### `background.js` — Tab-Management
+
+Überwacht Tab-Aktivitäten im Hintergrund und greift ein bevor Opera seine Startseite lädt.
+
+- Erkennt `opera://startpage/` und `chrome://startpage/`
+- Leitet per `chrome.tabs.update` auf `newtab.html` um
+- Prüft zusätzlich bei `onActivated` — auch im Hintergrund geladene Tabs werden sofort aktualisiert
+
+### `redirect.js` — In-Page Redirect
+
+Einige Opera-Systemprozesse sind so isoliert dass ein externer Eingriff nicht zuverlässig greift.
+
+- Wird als Content Script in Opera-Startseiten-Bereiche injiziert
+- Löst den Redirect bei `document_start` aus — minimale Verzögerung, kein Flackern
+
+---
+
+## Datenschutz
+
+Kein Tracking, keine Speicherung, keine externen Requests.
+Ausschließlich Standard-Browser-APIs — `chrome.tabs` — um die Kontrolle über den New Tab zurückzugewinnen.
+
+**100% lokal. 0% Analytics. Wie im gesamten Hellion NewTab Projekt.**
