 ## Project state
 
-**Phase 1 is scaffolded.** An `electron-vite` + React 18 + TypeScript app now lives at the repo root (`src/main`, `src/preload`, `src/renderer`). The prototype has been ported faithfully and renders against the **mock data** — full UI, git panel, four diff modes + Split, search, and the *simulated* terminals are all working. JetBrains Mono is bundled locally via `@fontsource/jetbrains-mono`; Prism is wired with the correct `markup-templating`→`php` load order; the renderer↔main clipboard bridge is in place (`src/preload/index.ts`).

 **Phase 2 (real integrations) — complete; DESIGN.md fully implemented.** The app is feature-complete against the functional spec (the only intentional exception is the separate Go-to-File overlay — `⌘P` aliases the unified search instead, per the resolved decision). Editor is writable (save · autosave · dirty tabs · discard); session restore brings back open tabs/active/view modes; close-dirty prompts Save/Don't-Save/Cancel. There's a vitest suite (`npm test`, 51 tests) + ESLint + electron-builder packaging. All over IPC through the preload bridge (`src/preload/index.ts`):
 - **Filesystem** — tree + in-memory content index, `chokidar` watch (`src/main/fs-service.ts`). The tree/index/search share one source of truth: `rg --files` (honors gitignore + `files.exclude`, includes dotfiles), with a recursive-walk fallback when ripgrep is unavailable.

 ## Design tokens
 
-Canonical source is the `:root` block in `design_handoff_helder_workbench/design/styles.css`. Surfaces are cool charcoal (`--bg-0` editor `#16171a` → `--bg-3` headers/tabs `#23262b`); single cool-blue accent `--accent #4d8dff`; git status `--add #5cbd6b` / `--del #e0696a` / `--mod #d8a85c` / `--ren #5aa6d6`. File-type icons are 15×15 monogram chips (no brand logos). Recreate UI icons as a small inline-SVG set (or Lucide), keeping the monogram chips for file types. Respect `prefers-reduced-motion`; keep motion subtle.
+Canonical source is **`docs/design/README.md`** plus the board `docs/design/Helder IDE.dc.html` (all screens at real pixel size) and `docs/design/screenshots/`. The tokens live in the `:root` block of `src/renderer/src/styles.css`.
+
+Four surfaces only: `--bg-0` editor/terminal `#101720` · `--bg-2` panels/chrome `#18202B` · `--sel`/`--border` `#232C39` · `--hover` `#1E2733`. Text ramp `#F4F5F4` → `#E4E7E6` → `#BAC0C0` → `#6C7783` → `#3A424C`. One accent, amber `#E8913A` (deep `#C4741F`, soft `#F0B476`), reserved for action, state and signal — never a decorative fill. Diff is teal `#8FBFB4` added and amber-deep `#C4741F` removed: **no green, no red anywhere**. Six muted syntax colours, all weight 400.
+
+Radii: 2px controls · 4px panels/menus · 8px overlays only. Row heights: 24px explorer · 26px source control · 28px status bar · 30px menu item · 34px view strip · 44px title bar. Hairlines are always 1px `#232C39`; the selection marker is a 2px amber rule.
+
+Row states: hover fills one step and does nothing else; selected takes `--sel` plus the 2px amber rule. Focus is always the 2px amber border plus a 2px 22% ring. Motion is colour-only, 160ms; the one exception is `blink` (stepped 1.1s) on the caret, the terminal cursor and the period in the wordmark. Respect `prefers-reduced-motion`.
+
+The older `design_handoff_helder_workbench/` prototype is superseded by `docs/design` — read it only for behaviour that the new board does not cover.
 
 ## Suggested implementation order (from README)
 
-1. Electron shell + frameless dark window; port tokens to CSS vars; bundle JetBrains Mono.
+1. Electron shell + frameless dark window; port tokens to CSS vars; bundle IBM Plex.
 2. Static layout: four resizable columns + title/status bars.
 3. Real file tree + open files into tabs (read-only) with Prism highlighting.
 4. Git panel from `git status` (read-only) → staging + commit → the four diff modes + Split.
