+
+Add four light UI and terminal skins: Paper Gray, Solarized Light, Catppuccin Latte, and Rosé Pine Dawn. The Skin picker now groups Light and Dark options, and each light skin ships a matching xterm ANSI palette plus `color-scheme: light` so native selects, date pickers and scrollbars stop rendering as dark OS widgets on a light page. Terminals set `minimumContrastRatio: 4.5` under a light skin (main terminal and teammate terminals both), which keeps CLI output that assumes a dark background readable, and `applyTerminalSkin()` now refreshes the zero-lag input overlay so typed-but-unflushed text does not keep the previous theme's colors.
+
+Elevated surfaces (modals, command palette, dropdowns, subagent and ultracode windows, file preview, attachment tray, mobile sheets) now resolve through shared `--floating-bg` / `--control-*` / `--banner-bg-*` / `--modal-backdrop` / `--elevated-shadow` tokens instead of hardcoded near-black rgba, so they follow whichever skin is active. On the Daylight skins this lifts modals slightly off the page background; OG Codeman pins its own near-black value to keep that palette neutral.
+
+Also defines twelve CSS compatibility aliases (`--bg-primary`, `--bg-secondary`, `--bg-tertiary`, `--text-primary`, `--text-secondary`, `--border-color`, `--accent-color`, `--success`, `--error`, `--danger`, `--font-mono`, `--shadow-lg`) that panels and overlays already referenced in about 79 places but which were never actually declared, so those rules silently resolved to nothing. Status badges and accent-tinted pills (search filter chips and result badges, session tab mode pills, respawn state, Ralph priority and circuit-breaker badges, tunnel and voice status, mobile case picker) no longer keep their pale light-on-dark ink under a light skin, where it measured 1.0 to 1.9:1 and made the search filter chips invisible.
+
+New static regression `test/skin-themes.test.ts` guards the four-way parity between the CSS token block, the xterm palette, the pre-paint allowlist and the Settings picker.

 **Gesture control** (camera hand-tracking overlay, opt-in, default OFF): `CODEMAN_GESTURE=1` makes the feature *available*; `gestureControlEnabled` turns it on. The bundle is injected by `renderIndexHtml` only when enabled, which is why that method is `async` and reads settings with `readSettings(true)` (a fresh read: a post-save reload lands inside the 2s cache TTL and would otherwise render the pre-toggle state). **Source lives in `packages/gesture-control/`; edit there, run `npm run build:gesture`, and commit the regenerated bundle** because dev serves the committed bundle with no runtime bundler.

 ### Theme skins

-**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.
+**Theme skins** (App Settings → Display): the `skin` setting selects a palette via a `data-skin` attribute on `<html>`. Dark values: `daylight-blue` (default), `daylight-green`, `og` (OG Codeman).

+
+**Adding a skin means touching four places, and each one fails silently on its own**: (1) the `html[data-skin="…"]` token block in `styles.css`; (2) the xterm ANSI palette in `CODEMAN_XTERM_THEMES` (terminal-ui.js) — a missing entry falls back to `daylight-blue`, so the terminal simply stays the wrong color; (3) the pre-paint allowlist array in `index.html` — a skin missing there is coerced to `daylight-blue` on every reload, which reads as "my theme keeps resetting"; (4) the `<select>` in App Settings. `test/skin-themes.test.ts` is the static four-way guard.
+
+**Light skins carry three extra obligations.** `color-scheme: light` on the `html[data-skin]` block, or the UA renders native `<select>` popups, date pickers and scrollbars as dark widgets on a light page. xterm `minimumContrastRatio: 4.5` (set at construction in terminal-ui.js **and** panels-ui.js for teammate terminals, and re-applied in `applyTerminalSkin()`), because CLIs emit colors chosen for dark backgrounds; dark skins keep `1` to avoid the per-cell contrast work. And `applyTerminalSkin()` must call `this._localEchoOverlay?.refreshFont()` — the zero-lag overlay **caches** the terminal fg/bg at construction, so without the refresh typed-but-not-yet-flushed text keeps the previous theme's dark backing after a live skin switch.
+
+**Shared surface tokens, not literals.** Elevated/floating surfaces resolve through `--floating-bg`, `--control-bg{,-hover}`, `--control-border{,-hover}`, `--banner-bg-a/b`, `--modal-backdrop` and `--elevated-shadow`, so modals, the command palette, dropdowns, subagent/ultracode windows, file previews and the mobile sheets follow the skin instead of hardcoded near-black rgba. ⚠️ Every skin that wants its own elevated look must override these — a skin that omits `--floating-bg` silently inherits the `:root` value, which is how the OG skin's near-black modals drifted slate. `styles.css` also defines **compatibility aliases** (`--bg-primary/secondary/tertiary`, `--text-primary/secondary`, `--border-color`, `--accent-color`, `--success`, `--error`, `--danger`, `--font-mono`, `--shadow-lg`) that forward to the canonical tokens; panels written against those names previously resolved to *nothing* (invalid at computed-value time), so the aliases are load-bearing, not cosmetic.
