 **Command palette + shortcut registry** (COD-151/153/157/192, #146): `Ctrl/Cmd/Alt+K` opens the session palette (fuzzy search over live sessions; "Browse all sessions" → the Session Manager modal backed by `GET /api/sessions/unified`); the quick-start case `<select>` is fronted by a searchable picker (`buildCasePickerOptions`/`formatCasePickerLabel` — remote cases render `name @ hostId`). Shortcuts live in a rebindable registry (`DEFAULT_SHORTCUTS`/`getShortcutRegistry()`/`matchesShortcutEvent()` in app.js; overrides persist under `settings.shortcutOverrides` via `saveAppSettingsToStorage`); App Settings → Shortcuts renders capture/disable rows; `Ctrl+?` opens the registry-driven overlay (footer links to the full `#helpModal` reference). ⚠️ Palette-chord keys must ALSO be swallowed in `attachCustomKeyEventHandler` (terminal-ui.js) or xterm writes the control byte (0x0B) into the PTY. ⚠️ `saveAppSettings()` rebuilds settings from the DOM — keys edited elsewhere (`shortcutOverrides`, `showTokenCount`, `showCost`) need explicit `_prev` carry-over.

 **Theme skins** (App Settings → Display): the `skin` setting selects a palette via a `data-skin` attribute on `<html>`. Values: `daylight-blue` (default), `daylight-green`, `og` (OG Codeman). CSS lives under `[data-skin="…"]` blocks in `styles.css`. To avoid a flash-of-wrong-theme, an **inline pre-paint script** in `index.html` (`<head>`) reads `localStorage['codeman:skin']` and sets `data-skin` before first paint; `settings-ui.js` `applySkin()` applies it live on save (sets `html[data-skin]` + `window.__codemanSkin`, syncs the standalone `codeman:skin` key with the settings blob, and calls terminal-ui.js `applyTerminalSkin()` to re-theme live terminals). `skin` is a **per-device/client-only** setting — it's destructured OUT of the server payload (settings-ui.js, alongside `localEchoEnabled`/`cjkInputEnabled`/`extendedKeyboardBar`), so it does NOT sync across devices.
 
-**Foldable settings identity**: responsive layout remains width-driven through `MobileDetection.getDeviceType()`, but the localStorage namespace/defaults use `MobileDetection.isHandheldDevice()` so an Android foldable keeps `codeman-app-settings-mobile` after unfolding past the desktop breakpoint. The stable handheld check prefers explicit phone/tablet/desktop UA tokens, then `navigator.userAgentData.mobile`; Android WebView is covered by the `Mobile` UA fallback. Do not switch per-device settings namespaces from instantaneous viewport width — a posture-triggered WebView reload would lose opt-in UI such as `showResponseViewer` and `extendedKeyboardBar`. Regression profile: `OPPO Find N5 (unfolded)` in `test/mobile/devices.ts`.
+**Custom branding + UI language** (App Settings → Display → Branding & Language): `displayName` is schema-validated (trimmed, 1–40 chars), server-synced, and changes user-facing browser branding/window titles only — NEVER rename npm package/CLI/API/storage/CSS/protocol identifiers. `language` is a per-device `en`/`zh-CN` display key, stripped from the server payload. `i18n.js` keeps English as the canonical source/fallback, observes newly inserted application DOM for dynamic copy, preserves source strings so live EN↔ZH switching is reversible, and skips terminal/response/file/session-name/user-content surfaces. User display names flow through `textContent`/attribute APIs and the server title's HTML escaper, never `innerHTML`.
