## Phase 1 — Token Foundation & Adoption (Week 1–2)

**Goal:** Every web app consumes tokens from `@bytelyst/design-tokens`. Zero hand-written CSS custom properties. Token Foundation 95% → 100%, Token Adoption (Web) 72% → 95%.

**Estimated effort:** 4–5 days

### 1.1 Add Missing Product Palettes to Canonical JSON

4 products have no palette in `bytelyst.tokens.json`. Add them so the generator can produce per-product CSS.

- [x] **ActionTrail** — add `color.actiontrail` section (accent, danger, surface variants) to `bytelyst.tokens.json`
- [x] **NoteLett** — add `color.notelett` section
- [x] **LocalMemGPT** — add `color.localmemgpt` section
- [x] **Local LLM Lab** — add `color.localllmlab` section
- [x] Run `generate.ts` and verify 4 new CSS + Swift + Kotlin files appear in `generated/`

**Files:** `packages/design-tokens/tokens/bytelyst.tokens.json`, `packages/design-tokens/scripts/generate.ts`

### 1.2 Generate Per-Product CSS and Wire Into Web Apps

The generator already produces per-product files. Each web app should import the generated CSS instead of hand-writing `globals.css` token blocks.

- [x] Publish `@bytelyst/design-tokens` generated output to Gitea npm registry (or use `file:` ref)
- [x] **ChronoMind** — replace hand-written `--cm-*` block in `globals.css` with `@import '@bytelyst/design-tokens/generated/css/chronomind.css'`
- [x] **JarvisJr** — replace `--jj-*` block
- [x] **NomGap** — replace `--ng-*` block; remove leaked `--ml-*` references
- [x] **ActionTrail** — replace `--at-*` block
- [x] **FlowMonk** — replace `--fm-*` block
- [x] **NoteLett** — replace `--nl-*` block; remove leaked `--ml-*` references
- [x] **LocalMemGPT** — replace `--lmg-*` block
- [x] **Local LLM Lab** — replace `--llm-*` block
- [x] Verify each app still renders correctly after swap (visual spot-check)

**Files per app:** `web/src/app/globals.css`, `package.json` (add dep)

### 1.3 Fix NomGap + NoteLett Token Prefix Leaks

Both apps leak `--ml-*` MindLyst tokens into their CSS.

- [x] **NomGap web** `globals.css` — find and replace all `--ml-*` references with `--ng-*`
- [x] **NoteLett web** `globals.css` — find and replace all `--ml-*` references with `--nl-*`
- [x] Grep-verify: `grep -rn '\-\-ml-' web/src/` returns 0 hits in both repos

### 1.4 Commit & Push

- [x] Commit per-repo: `fix(tokens): consume @bytelyst/design-tokens instead of hand-written CSS`
- [x] Push all repos to origin

### Phase 1 Score Impact

| Dimension            | Before | After    |
| -------------------- | ------ | -------- |
| Token Foundation     | 95%    | **100%** |
| Token Adoption (Web) | 72%    | **95%**  |
| **Overall**          | 65%    | **72%**  |

---

## Phase 2 — Shared Component Library (Week 2–4)

**Goal:** Create `@bytelyst/ui` with 12 shared primitives. Integrate shadcn/ui as the foundation. Component Library 15% → 70%.

**Estimated effort:** 8–10 days

### 2.1 Scaffold `@bytelyst/ui` Package

- [x] Create `packages/ui/` in `learning_ai_common_plat`
- [x] Initialize with `package.json` (`@bytelyst/ui`), `tsconfig.json`, Vitest
- [x] Add `react`, `react-dom`, `tailwindcss`, `class-variance-authority`, `clsx`, `tailwind-merge` as peer deps
- [x] Add `lucide-react` as peer dep (standardize icon library)
- [x] Configure exports: `@bytelyst/ui/button`, `@bytelyst/ui/input`, etc.
- [x] Add `README.md` with usage examples

### 2.2 Integrate shadcn/ui Primitives

Use Radix UI primitives (via shadcn/ui patterns) for accessible, composable components.

- [x] Add `@radix-ui/react-dialog`, `@radix-ui/react-toast`, `@radix-ui/react-select`, `@radix-ui/react-dropdown-menu`, `@radix-ui/react-tooltip`
- [x] Create `cn()` utility (clsx + tailwind-merge)
- [x] Configure Tailwind to consume `@bytelyst/design-tokens` CSS vars

### 2.3 Build 12 Core Components

Each component must: use design tokens, support dark/light, have ARIA, have focus-visible, be documented.

337 hardcoded hex values in NomGap mobile. The theme system exists but isn't consumed everywhere.

- [x] Run `grep -rn '#[0-9A-Fa-f]\{6\}' src/screens/ src/components/` to get full list
- [x] Replace each with `colors.xxx` from `useTheme()` hook
- [x] **Priority files:** JourneyScreen.tsx, NotificationSettings.tsx, BodyVisualization/\*
- [x] Target: <20 remaining (some are SVG/canvas constants that can't use theme)

### 4.7 Commit & Push

- [x] Commit per-repo: `feat(web): add theme toggle, responsive layout, toast feedback, empty states`

### Phase 4 Score Impact

| Dimension        | Before | After   |

- [x] Add `not-found.tsx` + `error.tsx` + `loading.tsx` to all 7 apps (30 min per app)
- [x] Add `:focus-visible` CSS rule to 6 apps missing it (5 min per app)
- [x] Add Lucide icons to ActionTrail + FlowMonk (currently no icon library)
- [x] Fix NomGap web 117 hardcoded hex in components (2–3 hours)
- [x] Fix FlowMonk 29 hardcoded hex in CSS (1 hour)
- [x] Fix LLM Lab 31 hardcoded hex in CSS (1 hour)

## Completion Criteria

The design system is at **100%** when:

1. Every web app imports tokens from `@bytelyst/design-tokens` — zero hand-written CSS custom property blocks
2. `@bytelyst/ui` exists with ≥10 shared components, consumed by ≥6 web apps
3. Every web app has `not-found.tsx`, `error.tsx`, `loading.tsx`
4. Every interactive element has `focus-visible`, `aria-label` (or visible text), and hover state
5. Every mutation shows toast feedback; every destructive action has confirmation
