Der größte Teil der Engine kommt aus Chat 2 (Message-Store, Channel-Logik, Hook-System), die meisten Tastenkürzel funktionieren weiterhin wie gewohnt. Was sich ändert: schärfere Privacy-Defaults von Haus aus, eigene Slash-Commands unter `/hellionchat`, kein Webinterface mehr, und mit v1.1.0 eine Theme-Engine als Schritt in Richtung eigenes UI-Look-and-Feel.

+**Hellion Chat 1.4.1 — Theme Engine Performance**
+
+Zweiter Sub-Patch der v1.4.x Polish-Sweep-Serie. Heap-Pressure
+aus dem Theme-Engine-Render-Pfad eliminiert, Custom-Theme-
+Hot-Reload überlebt transiente File-Locks beim Editor-Save.
+Plus zehnter Built-In und überarbeitete Author-Credits.
+
+- **ABGR-Cache auf den Theme-Records.** Beim Theme-Register
+  (Built-In oder Custom) werden alle Color-Slots einmalig in
+  ABGR-Pack-Form vor-konvertiert. HellionStyle.PushGlobal
+  liest aus dem Cache statt pro Slot pro Frame durch
+  ColourUtil.RgbaToAbgr zu jagen. Real gemessene
+  Frame-Time-Recovery: **~13 %** in typischer Render-Szene
+  (Plan-Erwartung war 2-6 % konservativ, real ~10-15 %)
+- **Custom-Theme File-Lock-Härtung.** Wenn der User ein
+  Theme-JSON gerade speichert während HellionChat reloaden
+  will, fängt der Loader jetzt explizit Sharing-Violation
+  und Lock-Violation ab. Last-Known-Good-Snapshot bleibt im
+  Picker, beim nächsten Tick wird automatisch retry'd —
+  vorher fiel das Theme aus der Liste bis zum Plugin-Reload
+- **Defensive Cache-Refresh beim Theme-Switch.** Falls ein
+  Theme auf einem alten Pfad ohne Cache-Fill in den Speicher
+  gekommen ist, holt Switch() das beim Anwenden nach
+- **Synthwave Sunset als zehnter Built-In.** Hot Magenta +
+  Cyan auf Mitternachts-Violett, 80s-Neon-Grid-Vibes für
+  Late-Night-Raids
+- **Author-Credits konsolidiert.** Brand-Themes laufen jetzt
+  unter „Hellion Forge". Mint Grove und Forge Merchantman
+  werden Carla Beleandis als Community-Geste zugeschrieben.
+
+Keine Schema-Bumps, keine User-sichtbaren Funktions-
+Änderungen außer dass die Frames in Theme-getrieben
+rendernden Szenen merklich glatter laufen und ein neues
+Theme im Picker steht.
