+Light-mode review fixes (after running the app):
+
+- **Warning chip is a wash, not a plate.** Bezel's `warning_muted` is a
+  strong amber (800 light / 200 dark) meant to carry white/black ink; on a
+  button it read as muddy brown. Both appearances now derive
+  `warning_muted` as a translucent wash of the `warning` token (10% light,
+  16% dark) and pair it with `warning`-toned labels; button hover/active
+  deepen the plate with the plate helpers, and `sync_legacy` maps
+  `warning_foreground` → `warning`. A contrast test measures the label
+  against the wash flattened onto the content plane.
+- **Inputs lost their grey.** Light `input_bg` was pure white; it is now
+  `neutral(0.950)`, one rung below the chrome grey like the old scale's
+  step-3 input plate. Dark stays bezel's white-at-3%.
+- **Dock planes move to `bg`.** The dock tab bar, title strip and panel
+  container read `bg` (white light / `#060606` dark — bezel's main panel),
+  matching the old near-white `panel_background`. Sidebar keeps `surface`
+  (the chrome grey).
+- **Active tab is a wash, not white.** The dock tab's selected plane is
+  `element_active` — one rung past the `element_hover` hover (darker in
+  light, brighter in dark). The segmented tab's active segment stays a
+  white raised plate with a shadow. `sync_legacy.tab_active_background`
+  follows.
+- **Sidebar text contrast.** Light `text_muted` moves from AppKit's
+  secondary label (~4:1, ~3.7:1 on the grey sidebar) to `neutral(0.45)`
+  (~5.3:1 on white), which also narrows the dark/light muted gap. Faint
+  stays AppKit-faint by design (placeholders).
+- `Brand::branded` now skips `apply` for the default brand so the test's
+  no-op assertion holds now that a shipped token (`text_muted`) diverges
+  from the AppKit ink `apply` would re-assert.
+- **Danger plates carry white ink in both appearances** (bezel's
+  destructive pairing — their `buttons.rs` hardcodes `gpui::white()` over
+  `danger_strong`): Danger button, error notification plate, title-bar
+  close hover, and `sync_base.destructive_foreground`. Visually a dark-mode
+  change only; light `on_accent` was already near-white.

+Semantic states, per bezel's own widgets (`crates/ui/src/widgets/{status,
+content,buttons}.rs`) — the recipes consumer banners, pills and state marks
+should follow:
+
+- **Strips (error/warning).** Bezel ships exactly two — "two tones, not a
+  level enum"; there is no info strip. Recipe: background = the semantic
+  token at 6% opacity, hairline ring = the same token at 20%, label and
+  leading triangle icon = the family's ink step at 90%, all at
+  `surface_radius()`. In coop tokens: error → bg `danger` at 6%, ring
+  `danger` at 20%, ink `danger_muted` (we kept bezel's ink step for danger);
+  warning → bg `warning_muted` (our wash token), ring `warning` at 20%, ink
+  `warning`.
+- **Success pill.** Bezel's `badge_active`: background = `success` at 12%,
+  ink = `success_muted` at 90%, `rounded_full`, no border.
+- **State dots.** No enum — the caller passes the tone
+  (`success`/`busy`/`warning`/`danger`, `text_faint` for "nothing yet") to a
+  6px bead.
+- **Destructive controls.** Bezel's plate is `danger_strong` with **white
+  ink in both appearances** (`gpui::white()` in their `buttons.rs`), hover
+  dims the whole control to 90% opacity, and role is independent of emphasis
+  (a quiet destructive control is a ghost with `danger_strong`-toned text).
+  coop now carries the white-ink rule in button, notification error plate,
+  title-bar close hover, and `sync_base.destructive_foreground`.
+- **Info.** No semantic tone — neutral copy on `text_muted`, or the quiet
+  hairline badge.
+- Known divergence (kept deliberately): bezel keeps `warning_muted` as the
+  family's ink token and bakes wash alphas at call sites; coop bakes the
+  warning wash into the `warning_muted` token (10% light / 16% dark) because
+  the legacy `warning_background` alias and the button plate need a token,
+  and pairs it with `warning`-toned ink. The danger family keeps bezel's
+  exact semantics (`danger` wash source, `danger_muted` ink, `danger_strong`
+  plate).
