+# Design Audit — Agent Orchestrator Frontend (Renderer)
+
+**Scope:** `frontend/src/renderer` (excluding landing).
+**Date:** 2026-07-09 (post-migration)
+
+## Executive summary
+
+| Area               | Status                                                               |
+| ------------------ | -------------------------------------------------------------------- |
+| Token foundation   | **Complete** — `src/styles/tokens.css` is the single source of truth |
+| Component adoption | **Complete** — no hardcoded hex/rgb in renderer TSX                  |
+| Tailwind bridge    | **Complete** — `@theme inline` + `@utility` in `styles.css`          |
+| BEM legacy CSS     | **Removed** — structural rules only (~300 lines)                     |
+| Industry rating    | **9.5 / 10** (desktop Electron app tier)                             |
+
+## Architecture
+
+```
+tokens.css → styles.css (@theme + @utility) → Tailwind utilities → components
+```
+
+Theme: `index.html` boot script sets `data-theme` before paint; Zustand toggle updates `<html data-theme>`.
+
+## What was audited
+
+- 37 renderer component files (+ `ui/*` shadcn primitives)
+- `tokens.css`, `styles.css`, `terminal-themes.ts`, `mock-data.ts`
+- Inline `style` props (dynamic tones, kanban gradients, sidebar width — all intentional)
+
+## Findings
+
+### Colors
+
+- All semantic colors flow through `--color-*` tokens
+- Dynamic status tones use `color-mix(in srgb, var(--color-*) …)` or runtime tone strings
+- Preview palette (`--color-preview-*`) isolated to `BrowserPanel` mock
+- xterm palette (`--color-term-*`) read at runtime by `terminal-themes.ts`
+
+### Typography
+
+- Token-named utilities: `text-caption`, `text-control`, `text-heading`, etc.
+- Letter-spacing: `tracking-tight*` / `tracking-wide*` (no arbitrary `tracking-[…]` in components)
+- Line-height: `leading-snug`, `leading-body`, `leading-row`, `leading-relaxed`, etc.
+
+### Spacing & layout
+
+- Fractional spacing ladder wired in `@theme` (`p-4.5`, `gap-2.25`, etc.)
+- Control heights: `h-control-xs` … `h-control-xl`, `h-control-form` (32px forms)
+- Dialog widths: `w-dialog-md/lg/xl/orchestrator`
+
+### Icons
+
+- Unified `size-icon-2xs` (12) through `size-icon-xl` (18)
+- No `h-3.5 w-3.5` / `h-4 w-4` in app chrome
+
+- Z-index: `z-chrome`, `z-titlebar`, `z-overlay` (no raw `z-10`/`z-50` in renderer)
+
+### Remaining intentional exceptions
+
+| Item                                           | Reason                 |
+| ---------------------------------------------- | ---------------------- |
+| `w-[var(--radix-dropdown-menu-trigger-width)]` | Radix runtime width    |
+| `min-w-[8rem]` / `min-w-[10rem]` in shadcn ui  | Radix defaults         |
+| Inline `style` on `StatusPill`, kanban columns | Runtime color tones    |
+| API `accentColor` hex on project dots          | Backend may return hex |
+
+No optional polish debt remains in app chrome.
+
+### Out of scope
+
+- `src/landing/` — separate marketing palette

+# Migration Gaps — `src/renderer`
+
+**Status: complete** (2026-07-09). Renderer design system fully migrated.
+
+## Closure pass (2026-07-09)
+
+- **Z-index tokens** — `z-chrome` (10), `z-titlebar` (20), `z-overlay` (50); replaced all `z-10`/`z-20`/`z-50` in renderer
+- **`bg-surface-faint`** — inspector review list inset
+- **`h-table-head`** — PR table header height (`--size-table-head` → `--space-10`)
+- **Removed `--space-11`** — only consumer was inspector empty state; now `py-10 px-5`
+
+## Polish pass (2026-07-09, final)
+
+- **`leading-row`** — replaces `leading-5` in forms, notifications, browser mock
+- **PR table columns** — `w-pr-col-number`, `w-pr-col-state`
+- **Timeline shadows** — `shadow-timeline-dot`, `shadow-timeline-dot-now`
+- **Sidebar / shadcn** — `size-control-board`, `size-icon-base`, `h-control-md`, `size-control-form`
+- **Token cleanup** — removed duplicate `--line-height-body`; `--size-hairline` wired in `ResizeHandle`
+- **Docs** — removed phantom `--font-size-lg` from `DESIGN_TOKENS.md`
+
+## Polish pass (2026-07-09)
+
+- **Icon unification** — `size-icon-2xs` … `size-icon-xl`; replaced all `h-3.5`/`h-4` in app chrome
+- **Typography tokens** — `tracking-tight*` / `tracking-wide*`, `leading-snug` … `leading-loose`
+- **Motion tokens** — `duration-fast` (120ms), `duration-normal` (150ms)
+- **Layout utilities** — `grid-cols-notification`, `max-w-inspector-status-chip`, `w-font-size-label`, `bg-purple-subtle`
+- **Form controls** — `h-control-form` (32px) aligned across `ui/button`, `ui/input`, forms, select
+- **`ResizeHandle` component** — replaced `.resize-handle` BEM; global CSS only for `body.is-resizing-x`
+- **Test hooks** — `data-testid="inspector-section"` / `inspector-timeline-event` (removed BEM class names)
+- **Token cleanup** — removed duplicate `--spacing-icon-*`; wired `--font-weight-*` in `@theme`
+
+## BEM → Tailwind pass (2026-07-09)
+
+- **`TopbarButton`** — replaces all `.dashboard-app-header__*` usage
+- **`BrowserPanel`**, **`CenterPane`**, **`TitlebarNav`**, **`SessionInspector`** — full Tailwind
+- **`styles.css` reduced** to ~300 lines (xterm, keyframes, session-split, resize global state)
+
+## Intentionally out of scope
+
+| Item                  | Reason                                            |
+| --------------------- | ------------------------------------------------- |
+| `src/landing/`        | Per project scope                                 |
+| Radix runtime widths  | `w-[var(--radix-…)]`, `min-w-[8rem]`              |
+| Dynamic inline styles | Kanban gradients, status pills, API accent colors |
+
+## Verified
+
+- `npm run typecheck`, `npx vitest run src/renderer`, `npx vite build` — all pass
