This introduces a persisted light/dark appearance setting, maps the desktop shell onto semantic theme tokens, and reworks the highest-traffic chat/settings surfaces so the new dark mode is usable without regressing the original light theme.
The same pass tightens markdown rendering for chat replies by improving inline code, table overflow handling, and safe external-link behavior so dark-mode content stays legible in real conversations.
Constraint: Preserve the existing light theme while adding a user-selectable dark theme in Settings > General
Constraint: Avoid introducing new dependencies for styling or markdown handling
Rejected: Replacing the light palette with a single dual-purpose palette | would risk broad visual regressions across the existing desktop UI
Rejected: Implementing dark mode only for shell chrome | leaves chat markdown, diffs, and permission flows visually broken
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: New desktop UI should use semantic theme variables instead of hard-coded color literals so both themes stay aligned
Tested: bun run lint; bun run test; bun run build; browser review of theme switching, provider/permission states, and chat surfaces
Not-tested: Prototype-style pages with remaining hard-coded colors (scheduled/session control mock surfaces) were not fully normalized in this change
- security: XSS sanitization with DOMPurify in Markdown/Mermaid/PermissionDialog;
path whitelist in filesystem API; fake keys in test/config files
- perf: fine-grained Zustand selectors in Sidebar/StatusBar/ContentRouter;
50ms throttle on streaming deltas; React.memo + useMemo in MessageList;
useRef for frequent keyboard shortcut state; AbortController 30s timeout
- leaks: WS session TTL timers (5-min cleanup on close); batch splice for
sdkMessages/stderrLines; folderPath validation in cronScheduler
- quality: optimistic update rollback in settingsStore; error state in
providerStore/teamStore; i18n for all hardcoded English strings
- docs: desktop architecture and features docs updated; VitePress nav fixed
