-# UI theme migration to bezel tokens
-
-Migrate `crates/theme` and `crates/ui` from the current `ThemeColors` /
-12-step-scale system to bezel's token set and theme architecture, keeping every
-existing UI element (button, dialog, dock, menu, ...) and its public API.
-
-Upstream: <https://github.com/crabtalk/bezel> — docs at
-<https://bezel.gallery> (append `.md` to any docs URL; `llms-full.txt` has the
-whole corpus). The source of truth for exact constants is bezel's repo:
-`crates/theme/src/theme/{mod,palettes,layout,typography,syntax}.rs`.
-
-> **Status:** Phases 0–1 are done on branch `new-theme` (except the manual
-> screenshot pass). The token core lives in `crates/theme/src/{color,palette,
-> brand,paint,layout,syntax,appearance}.rs`; the legacy fields remain as
-> derived aliases so the whole workspace still compiles. Divergences from the
-> original plan are noted inline.
-
-## Goal
-
-- One semantic token set (bezel's) with two designed palettes (dark, light).
-  Light is designed, not inverted — bezel's doc comment on
-  `crates/theme/src/lib.rs` is the reference for why.
-- Theming by `Brand` (tint hue, accent hue, base radius) plus a palette-builder
-  hook that survives light/dark switches.
-- Components read the theme global at paint time and take no color, font, or
-  size parameters. Radii derive from one base radius by ratio; spacing from
-  named constants.
-
-## Non-goals
-
-- No new components from bezel's catalog. The current element set stays.
-- No glass/material/vibrancy port in the first pass. The tokens exist in bezel's
-  `Theme`, but coop has no backdrop-blur surfaces today; port the fields as
-  inert defaults or omit them (see decision D6).
-- No `bezel` dependency. See D1.
-
-## Decisions
-
-- **D1 — Adapt, do not depend (verified 2026-10-09).** bezel 0.2.10 is built
-  against `bezel-gpui` 0.3.17, published from `crabtalk/zed`. coop is on
-  `gpui-pre` 0.3.8, a zed snapshot published by longbridge (huacnlee), and
-  `gpui-base` 0.7.1 (longbridge's gpui-kit) is built against that line with no
-  bezel-gpui build available. Adding `bezel` would put two gpui forks in the
-  graph — two type universes, the failure mode bezel's own docs warn about
-  first — and would strand `gpui-base` (BaseButton, component_traits,
-  scrollbars). So the theme *architecture* is ported: token names, palette
-  values, brand rotation, layout constants, and paint helpers are copied
-  verbatim from bezel's MIT-licensed source (each ported file carries an
-  attribution header), and gpui paths stay as they are. Revisit only if
-  `gpui-pre` and `bezel-gpui` ever unify.
-- **D2 — Keep component APIs.** `Button`, `Dialog`, `dock`, `menu`, `Sizable`,
-  `Size`, `ButtonVariant`, ... keep their names and signatures. Variants are
-  *re-derived* from the new tokens inside `crates/ui`. Callers only break where
-  they read theme tokens directly (there are ~370 such sites; Phase 3).
-- **D3 — Semantic tokens replace scales as the public API.** The Radix-style
-  12-step `ColorScale`/`ColorScaleSet` (`crates/theme/src/scale.rs`) stop being
-  public API. The oklch-derived palette generator replaces them internally.
-  `ActiveTheme` (`cx.theme()`) stays — it is coop's `Theme::of(cx)`.
-- **D4 — JSON themes become overrides.** `assets/themes/*.json` (aurora, 4x
-  catppuccin, flexoki, forest, ocean) and `ThemeRegistry` survive, but the
-  schema changes from "full `ThemeColors` dump" to "per-appearance override
-  deltas + optional `Brand`", applied over the built-in palette by the palette
-  builder. 8 small files, migrated by hand.
-- **D5 — `gpui-base` projection is re-derived, not dropped.** `sync_base`
-  (`crates/theme/src/lib.rs`) keeps feeding the base global (focus ring,
-  selection wash, scrollbars, overlay backdrops paint from it). The mapping is
-  rewritten against the new token names.
-- **D6 — Glass/material fields: omitted, not stubbed.** Phase 1 carried no
-  `vibrancy`/`glass`/`SurfaceSpec` fields at all — coop has no backdrop-blur
-  surface, and inert fields would only rot. `Brand` carries `tint`, `accent`,
-  `radius` and `ink` only. A glass port later adds the fields and the
-  renderer in one move.
-- **D7 — App chrome heights stay.** bezel's `TITLEBAR_HEIGHT = 38`,
-  `HEADER_HEIGHT = 44` are bezel-app values. coop keeps `TITLEBAR_HEIGHT = 36`,
-  `TABBAR_HEIGHT = 36`, `SIDEBAR_WIDTH = 240` (`crates/theme/src/lib.rs`) —
-  they are app layout, not tokens. `BASE_RADIUS` and the spacing constants are
-  adopted.
-
-## Token mapping
-
-Old → new. The census command to re-run at any time:
-
-```
-grep -rhoE "theme\(\)\.[a-z_0-9]+" --include="*.rs" crates desktop web | sort | uniq -c | sort -rn
-```
-
-Current usage counts (2026-10-09) are in the right column; zero means the token
-is only consumed via `sync_base` or not at all.

-| `tab_hover_background` | `element_hover` | | 2 |

-
-### Tokens coop gains
-
-`text_dim` (one notch below muted), `success` / `success_muted` / `busy`
-(message delivery and presence states), `accent` / `accent_strong` /
-`on_accent`, `input_bg`, `caret`, `band`, `surface_card` / `surface_dialog` /
-`surface_overlay` (elevation ladder), `surface_raised_hover`, `drop_line`,
-`code_text` / `code_wash` / `syntax: SyntaxPalette` / `diff_add` / `diff_del` /
-`diff_hunk_bg` (for `markdown.rs`), and the paint helpers `ink(alpha)` /
-`hairline(alpha)` / `wash(alpha)` / `scrim()`.
-
-### Tokens coop drops
-
-The `ColorScale`/`ColorScaleSet` public API, `ThemeColors` as a public struct,
-`element_*`/`secondary_*`/`ghost_element_*`/`tab_*`/`warning_*`/`danger_*`
-families, `icon*` tokens, `title_bar*`, `window_border`, `scrollbar_*` on the
-coop theme.
-
-## Phases
-
-Each phase is one PR (or a small series), compiles, and ships with the
-validation listed. Follow the PR hygiene in `AGENTS.md`.
-
-### Phase 0 — Baseline
-
-- [x] Record the token census (command above) as the migration checklist.
-- [x] Branch: work happens on `new-theme`.
-- [ ] Capture light/dark screenshots of the main surfaces: chat panel,
-      message hover/actions, relays & trace dialogs, settings dialog, group
-      (nip29) views, workspace tabs/dock, notifications. *(manual — run the
-      app before and after Phase 2/3)*
-
-### Phase 1 — Port the theme core into `crates/theme` (done)
-
-All steps keep the workspace compiling: the legacy token fields remain as
-values derived from the tokens (`ThemeColors::sync_legacy`), so the ~370 call
-sites build unchanged.
-
-- [x] **Palette generator.** `palette.rs`: bezel's two designed palettes,
-      constants copied verbatim from bezel's `palettes.rs` (oklch-derived
-      neutrals via `color.rs`). Light is designed, not inverted.
-- [x] **Token set.** `colors.rs`: the bezel token fields are flat on
-      `ThemeColors` (bg, surface ladder, hairlines, text ladder, solid,
-      accent trio, semantic colors, components, code & diff, syntax palette).
-      Legacy names resolve through `sync_legacy`. Deserialization refines over
-      the built-in dark palette (`#[serde(default)]`), so partial JSON still
-      loads.
-- [x] **Appearance plumbing.** `appearance.rs`: `AppearanceMode::{System,
-      Light, Dark}` (serde), `init`, `set_mode`, `apply`, `observe_window`.
-      `Theme::sync_system_appearance` routes through it. *Divergence: bezel's
-      macOS `NSAppearance` override syncing (so pinned themes restyle the
-      traffic lights) is not ported — needs an `objc` dependency; follow-up.*
-- [x] **Brand.** `brand.rs`: `Tint`, `BASE_COLORS` (Tailwind's five neutral
-      families), `TextInk`/`Ink` (AppKit + Accessible), `Brand { tint, accent,
-      radius, ink }` with the grey-rotation rule (grey tokens take the tint,
-      semantic tokens keep their hue, translucent ink is skipped).
-      `AppExt::set_brand` / `set_palette` install globals; the palette builder
-      runs first on every appearance install. A default brand is a strict
-      no-op so JSON themes are untouched until an app brands itself.
-- [x] **Layout constants.** `layout.rs`: `SPACE = 8`, `CONTENT_MARGIN = 20`,
-      `EDGE = 12`, `BASE_RADIUS = 8`, `BUTTON_HEIGHT = 24`,
-      `CONTROL_HEIGHT_SMALL = 20`, ratio functions (control 0.75x, button 1x,
-      panel 1.25x, surface 1.5x, bubble 2x), `inset_radius`. `Theme::radius`
-      is now 8 and `radius_lg` 12 (was 6/10) — intentional visual change.
-      coop's chrome heights stay (D7).
-- [x] **Typography (partial).** `Theme` gains `font_body` (defaults to
-      `font_family`) and `font_mono` (per-backend system mono). *Divergence:
-      bezel's `TextStyle`/`Metrics`/`Typeset` ladder and `ControlSize`/
-      `Sizing` are deferred to Phase 2, where the components that would use
-      them get reskinned.*
-- [x] **Paint helpers.** `paint.rs`: process-wide appearance mirror, `ink`,
-      `hairline`, `wash`, `scrim`, `band`, `INK_FILL_SCALE`/
-      `INK_HAIRLINE_SCALE`, `surface_shadows`, plate hover/active helpers.
-- [x] **Legacy JSON bridge.** `ThemeFamily::from_file` and the registry's
-      loader call `ThemeColors::rederive_tokens`, which best-effort maps an
-      old-schema theme's fields back onto the tokens (fields with no legacy
-      source — `success`, `busy`, syntax, diff — keep the built-in palette's
-      value for that appearance). Phase 4 replaces the schema; this bridge is
-      what keeps the 8 shipped themes usable in the meantime.
-- [x] **`sync_base` rewrite.** Projects the new tokens onto `gpui_base::Theme`
-      (bg→background, text→foreground, solid→primary, surface_raised→secondary,
-      surface_card→muted, element_hover→accent, danger_strong→destructive,
-      on_solid/on_accent→*_foreground, border→border/input, ring→ring,
-      selection→selection).
-- [x] **Contrast tests.** `tests/contrast.rs`: text ≥ 13.9:1 on bg and
-      surface in both appearances (measured 14.4/15.1), muted ≥ 3.9:1,
-      faint ≥ 1.8:1 (AppKit ink lands below WCAG AA by design), light-vs-dark
-      parity for primary text within 0.7, default brand is a no-op, brand
-      rotation moves greys but not semantic hues, legacy aliases track
-      tokens, and a legacy-JSON round trip. *Note: bezel's docs claim ~0.5
-      parity for every text role; the shipped AppKit ink only delivers that
-      for primary text, so the test asserts floors for muted/faint instead.*
-- [x] `cargo test -p theme` (11 tests) and `cargo check --workspace` green;
-      clippy clean.
-- [ ] Pixel review of the running app against Phase 0 screenshots (needs the
-      manual screenshot pass first). The palette swap is intentionally visible:
-      neutral `#060606`/`#0d0d0d` surfaces replace the grey scale, hover/active
-      washes are neutral ink, focus rings are hairlines, cursor/selection match
-      macOS defaults.
-
-### Phase 2 — Reskin `crates/ui`
-
-Keep public APIs (D2). Per file, replace old token reads with new tokens,
-radii with ratio functions, ad-hoc spacing with `SPACE` steps where it is a
-real deviation, and state washes with the paint helpers.
-
-- [x] `button.rs` — variant table: Primary → `solid`/`on_solid` +
-      `surface_raised_hover`-style plate hover; Secondary →
-      `surface_raised` + `border` + `text`; Danger → `danger_strong` +
-      `on_accent`; Warning → `warning_muted` chip treatment; Ghost →
-      transparent + `element_hover`/`element_active`; Custom stays (sources
-      defaults from new tokens). Size → bezel `ControlSize` ladder values via
-      the existing `Size` enum. Radius: `button_radius()`, `bubble_radius()`
-      when `rounded`. *(Size ladder heights kept — bezel's 24px control
-      heights are a consumer-visible layout change, deferred.)*
-- [x] `input/` — `input_bg`, `border_faint` resting / `border_strong` focus,
-      `ring`, `caret`, `selection`, `text_faint` placeholder. *(coop's Input
-      paints no frame border/ring of its own — focus mechanics untouched;
-      `InputEditorStyle::border` now `border_faint`, placeholder reaches
-      gpui-base's `muted_foreground`, now `text_faint`.)*
-- [x] `dialog.rs` — `surface_dialog` over `scrim(SCRIM_ALPHA_DARK)`,
-      `surface_radius()`, `surface_shadows()` (entrance animation scales the
-      helper's shadow alphas).
-- [x] `popover.rs`, `menu/` — `surface_overlay`, hairline border,
-      `popover_surface` stub (D6: plain wash for now). *(The floating plate
-      is `StyledExt::popover_style` in styled.rs; popover.rs itself paints no
-      theme values. Menu item corners are concentric:
-      `inset_radius(surface_radius(), 4)`.)*
-- [x] `tab.rs` — mapping table row: `bg` active plane, `element_hover`
-      hover, `text_muted`/`text` labels, `border_faint` separators. *(No
-      separator was painted before; none added — structure frozen. Segmented
-      track is `surface`.)*
-- [x] `nav.rs`, `nav_item.rs` — `element_hover`/`element_active` states,
-      `accent` selection markers. *(Resting labels are now `text_muted` —
-      intentional visible change; radius 12→8.)*
-- [x] `title_bar.rs` — the crate never read `title_bar`/`title_bar_inactive`
-      (consumers paint the strip); close-button danger hover reskinned to
-      `danger_strong`/`on_accent`/`plate_active`. Drag handlers and heights
-      untouched.
-- [x] `tooltip.rs` — `surface_overlay` plate, `text` label,
-      `control_radius()`.
-- [x] `switch.rs` — on: `accent_strong` track + `on_solid` knob; off:
-      `input_bg` track + `border`.
-- [x] `indicator.rs`, `kbd.rs` — indicator turned out to be the loading
-      spinner and paints no theme values (no status dots exist in `crates/ui`
-      — the `success`/`busy`/`danger` mapping lands at consumer call sites in
-      Phase 3). kbd: `surface_raised` + `border_faint` + `text_muted`.
-- [x] `avatar.rs` — no ring/border is painted today; dropped the
-      `ghost_element_background` underlay. Blob behavior kept.
-- [x] `message.rs` — `text_dim` on the author/timestamp row, `text_faint`
-      welcome body, `element_hover` row wash. *(No bubbles, delivery states,
-      composer strips or report banners live in this file — those are
-      consumer-side, Phase 3.)*
-- [x] `markdown.rs` — `code_text`/`code_wash` (added `with_inline_code`),
-      heading hierarchy (`with_heading`: h1–h3 `text`, h4–h6 `text_muted`),
-      links `accent`. *(Fenced-code highlighting comes from gpui-base's theme
-      via `sync_base`; `SyntaxPalette` stays unconsumed until a coop-side
-      highlighter exists.)*
-- [x] `notification.rs` — `surface_overlay` plate + `surface_radius()` +
-      `surface_shadows()`; error is a full `danger_strong` plate with
-      `on_accent`, success/warning icons `success`/`warning`.
-- [x] `group_box.rs` — `surface` plate, `panel_radius()`. *(No border or
-      header strip is painted today; adding them is a design change, deferred
-      to Phase 3/4 review.)*
-- [x] `dock/`, `resizable/` — `drop_target`, `drop_line`, `border_faint`.
-      *(Tab-insertion line and drop-region outline both use `drop_line` now —
-      slightly more prominent than the old muted outline, intentional. Drag
-      preview/empty-space drag-over also reskinned.)*
-- [x] `scroll/` — verified: zero theme reads; scrollbar paint comes from
-      gpui-base via `sync_base`, `ScrollbarMode` still lands.
-- [x] `root.rs` — `bg` plane, `surface_shadows()` on the window frame (now
-      gated on `cx.theme().shadow`); decoration consts untouched.
-- [x] `icon.rs` — default tone `text_muted` (was `icon`); `IconName` set and
-      APIs unchanged.
-- [x] `styled.rs` — `divider()` → `border_faint`; `popover_style()` →
-      `surface_overlay` + `px(surface_radius())` + `surface_shadows()` gated
-      on `cx.theme().shadow` (was always-on `shadow_md`). Keep
-      `h_flex`/`v_flex` names (bezel's `stack::row`/`column` equivalents).
-- [x] `animation.rs` — left as-is this pass; bezel's named-motion catalog is
-      a follow-up.
-
-Outcome: `theme::plate_hover`/`plate_active` were made public (wrappers over
-the crate-internal `*_for` helpers) so `crates/ui` can reskin opaque plates.
-Zero legacy-token reads remain in `crates/ui` (the Phase 3 grep already
-passes inside this crate); `cargo check -p ui`, `cargo check --workspace`,
-`cargo test -p theme` (11 tests) and `cargo clippy -p ui -p theme` are green.
-Public APIs, element structure, sizes and heights unchanged (D2, D7).
-
-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.
-
-Validation remaining: run desktop, walk every component in light/dark
-against the Phase 0 screenshots.
-
-### Phase 3 — Migrate consumers
-
-Mechanical per the mapping table; ~370 sites across 8 crates. Use the
-deprecated accessors as the worklist — the goal is zero deprecated hits.
-
-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).
-
-- [x] `crates/chat_ui` — all 20 legacy tokens migrated in `lib.rs` (~46
-      sites). Radius rulings: message media images → `bubble_radius()`;
-      reaction/file chips and composer tiles → `control_radius()`; trace
-      callout → `panel_radius()`; warning/danger report strips and the
-      floating hover toolbar → `surface_radius()`. `elevated_surface`
-      split: relay chips / reply-row hover → `surface_raised`, success
-      report box → `surface_card`. Warning sites got the bezel strip
-      treatment (`warning_muted` wash + `warning` ink); failed-report rows
-      got the error-strip recipe (`danger` @6% + `danger_muted` @90%).
-- [x] `crates/workspace` — 58 sites across 18 files. Radius: warning
-      strips → `surface_radius()`; input plates and control rows →
-      `button_radius()`; request-count chip → `control_radius()`; browse
-      cards and empty states → `panel_radius()`. `text_danger` → `danger`
-      everywhere (each site was its view's only error signal). The "new
-      requests" bead in the sidebar (old `cursor` token, an accent blue)
-      → `accent`, not `caret` — it is an attention marker, not a text
-      cursor. Settings dialog's `Theme::change` calls left for Phase 4.
-- [x] `crates/nip29_ui`, `crates/nip4e` — 27 sites. Activity-row hover →
-      `element_hover` (it interleaves with `MessageRow` in one list);
-      message media → `bubble_radius()`; chips/pills → `control_radius()`;
-      nip4e plates → `surface_card`. Flag for the design pass: the pin
-      chip now paints `solid` under a `text_muted` label — that pairing
-      predates the migration (old `element_background` + `text_muted`);
-      if it reads loud, its label should become `on_solid`.
-- [x] `crates/settings`, `desktop`, `web` — verified zero theme-token
-      reads (their appearance wiring is Phase 4 scope).
-- [x] Replace `radius`/`radius_lg` with the ratio function the element is
-      — done per crate by the agents above (not sed); rulings recorded
-      per bullet.
-- [x] `cargo check --workspace` clean; the Phase 3 grep gate (extended
-      with `surface_background`, `background`, `cursor`, `drop_target_background`)
-      returns nothing across crates and `desktop`/`web`.
-
-Follow-ups noted: chat_ui paints delivery/status marks with hardcoded
-`gpui::green()`/`red()` — candidates for the `success`/`busy`/`danger`
-status-dot recipe in a later polish pass; warning strips carry no 20%-alpha
-ring (no border existed; adding one is a structure change).
-
-### Phase 4 — Settings, appearance, and the removal of the multi-theme system (done)
-
-The original plan (appearance_mode with back-compat, registry re-schema,
-brand-izing the 8 shipped JSONs) was superseded by a decision: **coop no
-longer ships multiple themes**. The bezel token palettes (dark and light,
-optionally rotated by a `Brand`) are the only theming surface. Done:
-
-- [x] `crates/settings`: persisted `theme_mode: ThemeMode` →
-      `appearance_mode: AppearanceMode` with
-      `#[serde(default, alias = "theme_mode")]` — an old config's pinned
-      Light/Dark survives; absence falls back to `System`. Round-trip tests
-      cover both. `set_theme`/`reset_theme` deleted; `apply_theme` is now
-      `cx.set_appearance_mode(mode)`.
-- [x] `ThemeRegistry`, `assets/themes/*.json` (8 files), and the
-      `themes/**/*` asset embed are deleted. `theme::init` is
-      `appearance::init` + scrollbar sync.
-- [x] `ThemeFamily`, `from_file`/`from_assets`, the theme picker dialog
-      (`theme_selector` + `Command::ToggleTheme` + its header/greeter menu
-      entries), and the settings dialog's "Reset theme" row are deleted.
-      The appearance picker is now System/Light/Dark via
-      `AppearanceMode::ALL` and `AppExt::set_appearance_mode`.
-- [x] The old-schema JSON bridge (`rederive_tokens`, `sync_legacy`,
-      `legacy_default`) is gone with the schema.
-
-### Phase 5 — Removal and docs (done)
-
-- [x] Deleted `ThemeColors` legacy fields (~60), `ColorScale`/`ColorScaleSet`
-      (`scale.rs`), `ThemeColors::light/dark` wrappers, `Theme::apply_theme`,
-      and the `Theme` fields `theme: Rc<ThemeFamily>`, `radius`, `radius_lg`
-      (every site reads the ratio functions now). `ThemeColors` stays public:
-      it *is* the token set, in the bezel style.
-- [x] `crates/ui/src/scroll/scrollable.rs` no longer paints scrollbar colors
-      from coop tokens — gpui-base's `Scrollbar` paints from its own global
-      theme (kept in step by `sync_base`'s scrollbar mode), with base's
-      defaults for thumb/track.
-- [x] `ui::init` boot order verified: `theme::init` (appearance::init)
-      runs before the first window in desktop and web; workspace still
-      observes window appearance for live System flips. Desktop/web
-      comments updated.
-- [x] Final census: only new token names remain; workspace compiles; tests
-      green (theme 5, settings 2 incl. serde compat, 52 chat_ui).
-
-Follow-ups noted: chat_ui's hardcoded `gpui::green()`/`red()` status marks
-are candidates for the `success`/`busy`/`danger` status-dot recipe; the
-nip29 pin chip pairs `solid` with a `text_muted` label (predates the
-migration) — flip its label to `on_solid` if it reads loud.
-
-### Phase 5 — Removal and docs
-
-*(Executed together with Phase 4 — see above.)*
-
-- [x] Delete `ThemeColors`, the deprecated aliases, `ColorScale`/
-      `ColorScaleSet` public exports (`scale.rs` either goes private as the
-      palette generator's internal or is deleted), `ThemeMode`.
-- [x] `crates/ui/src/lib.rs`: `theme::init` already runs `appearance::init`;
-      verify `ui::init`'s callers boot the theme before the first window, and
-      that every opened window observes appearance changes
-      (`theme::observe_window` or workspace's sync-on-activation hook).
-- [x] Update `README`/docs mentions of theme customization; document
-      `Brand` + override JSON as the two supported ways to theme coop.
-- [x] Final census run: only new token names remain.
-
-## Risks
-
-- **Fork mismatch (D1).** If `gpui-pre` and `bezel-gpui` ever unify, a direct
-  `bezel` dependency becomes possible and Phase 1's ported code could be
-  swapped for the real crate. Do not half-adopt (bezel + own gpui) — that is
-  the two-gpuis trap.
-- **Light regressions.** coop's light palettes today are scale-derived; the
-  new light palette is designed. Expect intentional differences in surface
-  order and accent tones; judge against the Phase 0 screenshots, and record
-  intentional deltas in the PR description.
-- **gpui-base drift.** Anything base paints (focus ring, text selection,
-  scrollbars, overlay backdrops) bypasses coop tokens. `sync_base` is the only
-  seam — keep it total, and keep it on the appearance-change path.
-- **Init order.** `appearance::init` must run before the first window opens or
-  the first frame paints the wrong palette; `observe_window` must be attached
-  per window for live light/dark flips.
-- **Settings serde.** Old persisted `theme_mode` values must not break load;
-  covered by Phase 4 compat shim and a round-trip test.
-- **No component gallery.** coop has no bezel-gallery equivalent; the Phase 0
-  screenshots are the review surface. If Phase 2 review gets painful, a
-  throwaway debug window that renders one of each component is cheaper than
-  regressions.
