+**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.

+**Hellion Chat 1.4.2 — ChatLog Frame-Hot-Path**
+
+Dritter Sub-Patch der v1.4.x Polish-Sweep-Serie. Drei
+Per-Frame-Allokations-Quellen aus dem ChatLogWindow-Render-
+Pfad und der Settings-StatusBar eliminiert.
+
+- **Card-Mode-Border-Loop entlastet.** DrawMessages hebt
+  Theme, DrawList, Window-Left, Window-Right und die ABGR-
+  Border-Color einmalig vor den Per-Message-Loop. Bei 100
+  sichtbaren Messages sind das gut 500 redundante P/Invokes
+  und Property-Reads, die der Hoist eliminiert. Pop-Out-
+  Heavy-Setups (mehrere parallele Chat-Windows) profitieren
+  proportional, weil der Hoist pro DrawMessages-Call greift,
+  also pro Window
+- **Auto-Tell Tab-Tint und Icon gecached.** Die Hash-Color-
+  Berechnung für Auto-Tell-Tabs lief pro Tab pro Frame, mit
+  zwei String-Allokationen pro Tab (eine für Tint-Hash, eine
+  für Icon-Hash). Der neue TabTintCache liest pre-computed
+  Werte aus dem Tab und rechnet nur neu wenn das Tell-Target
+  drifted. Beide Caches haben separate Validation-Keys, also
+  keine Cross-Invalidation zwischen Tint- und Icon-Pfad.
+  AutoTellTabTint selbst bleibt pure Hash-Helper, weiterhin
+  ohne Tab-Awareness
+- **StatusBar-Aggregation hinter Cache-Gate.** Die Status-
+  Leiste am unteren Window-Rand summiert die Tab-Message-
+  Counts und zählt die Auto-Tell-Tabs pro Frame. Der Cache-
+  Gate (1 Sekunde) lag bisher hinter den LINQ-Pfaden, also
+  liefen Sum und Count trotzdem pro Frame. Jetzt vor dem
+  Gate, plus die LINQ-Pfade durch eine Single-Pass-Foreach
+  ersetzt. Die Aggregation läuft auf etwa 1 % der Frames
+
+Realistische Frame-Time-Recovery: 2-5 % in typischen Szenen,
+Pop-Out-Heavy-Setups potenziell mehr durch die Card-Border-
+Multiplikation pro Window.
+
+Keine Schema-Bumps, keine User-sichtbaren Funktions-
+Änderungen außer dass die Frames im Chat-Log und in der
+Settings-Statusleiste merklich glatter laufen.

+  **Hellion Chat 1.4.2 — ChatLog Frame-Hot-Path**
+
+  Third sub-patch of the v1.4.x Polish Sweep series. Per-frame
+  allocations from the chat-log render path eliminated.
+
+  - DrawMessages card-mode hoists theme/drawList/winLeft/winRight/
+    borderColorAbgr out of the per-message loop. About 500
+    redundant calls per frame at 100 visible messages, multiplied
+    by every pop-out window
+  - Auto-tell tab tint and icon use a per-tab cache. Hash
+    computation and string allocation only happen when the tell
+    target name or world drifts. AutoTellTabTint stays a pure
+    hash helper; cache lives in a thin TabTintCache wrapper
+  - Status bar gates its tab aggregation behind the same
+    one-second cache it already used for the format strings.
+    LINQ Sum and Count replaced with a single foreach pass
+    that runs on roughly 1% of frames
+
+  Realistic frame-time recovery: 2-5% in typical scenes, more

+
+  Second sub-patch of the v1.4.x Polish Sweep series. Heap
+  pressure from the theme engine's per-frame render path
+  removed, plus a tenth built-in theme and hardening for
+  the custom-theme hot-reload.
+
+  - Theme records carry a pre-computed ABGR-packed cache
+    for every color slot; cache is filled when the theme
+    is registered and refreshed defensively on every
+    Switch()
+  - HellionStyle.PushGlobal reads ABGR values from the
+    cache instead of calling ColourUtil.RgbaToAbgr per
+    slot per frame; ~13 % render-time recovery measured
+    in typical scenes (plan estimate was 2–6 %, real
+    ~10–15 %)
+  - ThemeRegistry custom-theme reload distinguishes a
+    recoverable file lock (editor mid-save) from a
+    permanent IO failure; locked themes keep their
+    last-known-good snapshot and retry on the next
+    lookup instead of dropping out of the picker
+  - New built-in: Synthwave Sunset — Hot Magenta + Cyan
+    on midnight violet, 80s neon-grid vibes; tenth theme
+    in the picker
+  - Author credits refreshed: brand themes are credited
+    as "Hellion Forge"; Mint Grove and Forge Merchantman
+    now credited to Carla Beleandis as a community thanks

-  no settings touched — just more colour options.
-
-  - **Night Blue** — Royal Blue on deep marine. Cool tech-dashboard
-    mood, distinct from the brand themes.
-  - **Indigo Violet** — Royal Violet on deep indigo with a turquoise-
-    mint counter for an aurora glitter feel. Sister to Event Horizon
-    but darker and denser; the turquoise accent keeps the two
-    distinguishable.
-  - **Forge Merchantman** — Patina bronze on workshop slate, warm
-    amber counter. Hellion Forge given a theme of its own — sister
-    to Hellion Arctic but greener and warmer instead of cold cyan.
-  - **Hellion Spectrum** — Deuteran/Protan-safe channel colours
-    using Wong/Okabe-Ito palette tones. Channel identity (Tell pink,
-    Yell yellow, Shout orange, Party blue, FC green) is preserved;
-    tones are chosen so each channel stays distinguishable under
-    red-green colour vision deficiency. Covers the ~99% of CVD cases

+## Hellion Chat 1.4.2 — ChatLog Frame-Hot-Path
+
+Third sub-patch of the v1.4.x Polish Sweep series. Per-frame
+allocations from the chat-log render path eliminated.
+
+- `DrawMessages` card-mode hoists `theme`/`drawList`/`winLeft`/
+  `winRight`/`borderColorAbgr` out of the per-message loop. About
+  500 redundant calls per frame at 100 visible messages, multiplied
+  by every pop-out window
+- Auto-tell tab tint and icon use a per-tab cache. Hash
+  computation and string allocation only happen when the tell
+  target name or world drifts. `AutoTellTabTint` stays a pure
+  hash helper; cache lives in a thin `TabTintCache` wrapper
+- Status bar gates its tab aggregation behind the same
+  one-second cache it already used for the format strings.
+  LINQ `Sum` and `Count` replaced with a single `foreach` pass
+  that runs on roughly 1 % of frames
+
+Realistic frame-time recovery: 2-5 % in typical scenes, more
+on pop-out-heavy setups because the card-border hoist scales
+per window.
+
+Modding & support: join Hellion Forge — https://discord.gg/X9V7Kcv5gR

+
+## Hellion Chat 1.4.1 — Theme Engine Performance
+
+Second sub-patch of the v1.4.x Polish Sweep series. Heap
+pressure from the theme engine's per-frame render path
+removed, plus a tenth built-in theme and hardening for
+the custom-theme hot-reload.
+
+- Theme records carry a pre-computed ABGR-packed cache
+  for every color slot; cache is filled when the theme
+  is registered and refreshed defensively on every
+  `Switch()`
+- `HellionStyle.PushGlobal` reads ABGR values from the
+  cache instead of calling `ColourUtil.RgbaToAbgr` per
+  slot per frame; ~13 % render-time recovery measured
+  in typical scenes (plan estimate was 2–6 %, real
+  ~10–15 %)
+- `ThemeRegistry` custom-theme reload distinguishes a
+  recoverable file lock (editor mid-save) from a
+  permanent IO failure; locked themes keep their
+  last-known-good snapshot and retry on the next
+  lookup instead of dropping out of the picker
+- New built-in: **Synthwave Sunset** — Hot Magenta + Cyan
+  on midnight violet, 80s neon-grid vibes; tenth theme
+  in the picker
+- Author credits refreshed: brand themes are credited
+  as "Hellion Forge"; **Mint Grove** and **Forge
+  Merchantman** now credited to **Carla Beleandis** as
+  a community thanks
+
+No schema bump, no user-visible behaviour change other
+than smoother frames on GC-sensitive setups and one
+additional colour option.
