# Phase 7 — UI Review
**Audited:** 2026-04-23
**Baseline:** AI_RULES.md & PROJECT_ARCHITECTURE.md
**Screenshots:** Captured to `.planning/ui-reviews/07-20260423-160359/`
## Pillar Scores
| Pillar | Score | Key Finding |
|--------|-------|-------------|
| 1. Copywriting | 3/4 | Descriptive labels used ("Discard", "Subtract"), but generic "Cancel" buttons remain. |
| 2. Visuals | 4/4 | Excellent adherence to `max-w-7xl` and Lucide icons. Unified headers implemented. |
| 3. Color | 4/4 | Good 60/30/10 split. No arbitrary hex codes in UI layers. |
| 4. Typography | 2/4 | **CRITICAL:** `globals.css` uses `font-weight: 600` for headers; `font-medium` (500) used in several components. Rule requires `font-normal` (400) only. |
| 5. Spacing | 4/4 | Consistent use of responsive `space-y-` and `p-` scales as per architecture. |
| 6. Experience Design | 4/4 | Strong sync indicators, loading states, and confirmation safeguards. |
**Overall Score:** 21/24
---
## Detailed Findings
### Pillar 4: Typography (2/4)
- **Violation:** `frontend/app/globals.css:26` defines `h1-h6` with `font-weight: 600`.
- **Violation:** `frontend/components/admin/DatabaseManager.tsx:141` and others use `font-medium`.
- **Requirement:** AI_RULES.md Section 3 explicitly forbids bold fonts and requires `font-normal` throughout.
### Pillar 1: Copywriting (3/4)
- **Pro:** UI uses descriptive actions: "Force Backup", "Save LDAP Policy", "Subtract 1 from Stock".
- **Improvement:** "DELETE" (uppercase) is used in confirmation modals. While good for safety, it technically bypasses the "NO UPPERCASE" rule. Consider using Title Case "Delete" with a specific background color instead.
### Pillar 2: Visuals (4/4)
- **Success:** Main pages correctly utilize `max-w-7xl` with `mx-auto`.
- **Success:** Unified headers with icon boxes found in `admin/page.tsx` and `page.tsx`.
### Pillar 6: Experience Design (4/4)
- **Success:** Offline/Online status indicators are prominent and animated.
- **Success:** Destructive actions like "Delete Item" and "Logout" utilize `window.confirm` or high-fidelity modals as required.
---
### Top 3 Priority Fixes
1. **Remove Font Weights** — Remove `font-weight: 600` from `globals.css` (headers) and replace all `font-medium` with `font-normal`. Hierarchy must rely on size and color only.
2. **Contextual CTA Labels** — Replace generic "Cancel" and "OK" with contextual verbs (e.g., "Keep Item", "Discard Changes") to improve copywriting fidelity.
3. **Focus State Consistency** — Ensure all interactive elements (buttons, inputs) have consistent `focus-visible:ring-2` styling for accessibility.
---
**Files Audited:**
- `frontend/app/globals.css`
- `frontend/app/page.tsx`
- `frontend/app/admin/page.tsx`
- `frontend/components/PageShell.tsx`
- `frontend/components/admin/DatabaseManager.tsx`

# Color System Architecture: Single Source of Truth
**Status**: ✅ IMPLEMENTED
**Commit**: e715afd8
**Date**: 2026-04-25
---
## Problem Solved
Color definitions were previously duplicated in two locations:
- `frontend/tailwind.config.ts` — Tailwind CSS utility classes (e.g., `bg-primary`)
- `frontend/app/globals.css` — CSS custom properties (e.g., `--primary`)
This created a **DRY violation** where changing a color required edits in 2 places, with high risk of inconsistency.
---
## New Architecture
### 1. Single Source of Truth: `frontend/colors.mjs`
```javascript
// frontend/colors.mjs — The authoritative color definitions
export const colors = {
background: "#131313",
primary: {
DEFAULT: "#ffb781",
container: "#f58618",
// ... all color variants
},
// ... 40+ colors from DESIGN.md
};
export const spacing = {
unit: "4px",
"stack-sm": "8px",
// ... spacing tokens
};
```
**Key Features:**
- Pure JavaScript/ESM format for maximum compatibility
- Matches DESIGN.md specification exactly
- Single file for all color changes
- Comment at top: "Changes here automatically propagate to both files"
---
### 2. Automated CSS Generation: `frontend/scripts/generate-css-vars.mjs`
A build-time script that:
1. Reads `colors.mjs`
2. Flattens nested color objects (e.g., `primary.DEFAULT``--primary-DEFAULT`)
3. Generates CSS custom properties organized by category
4. Injects into `frontend/app/globals.css` `:root` block
5. Preserves all other CSS code unchanged
**Execution:**
```bash
node frontend/scripts/generate-css-vars.mjs
# Output: ✓ Generated CSS variables in globals.css from colors.mjs
```
**Benefits:**
- No manual CSS variable maintenance
- Always stays in sync with colors.mjs
- Runs automatically before every build
---
### 3. Import in Tailwind Config: `frontend/tailwind.config.ts`
```typescript
import { colors as colorsDefinition } from "./colors.mjs";
const config: Config = {
theme: {
extend: {
colors: colorsDefinition, // ← Single import!
// ...
},
},
};
```
**Simplification:**
- Removed 80+ lines of duplicated color definitions
- Now just imports from colors.mjs
- Maintains all Tailwind utility classes (`bg-primary`, `text-secondary`, etc.)
---
## Build Integration
### Frontend Build (`frontend/package.json`)
```json
{
"scripts": {
"generate-css-vars": "node scripts/generate-css-vars.mjs",
"dev": "npm run generate-css-vars && next dev",
"build": "npm run generate-css-vars && next build"
}
}
```
**Flow:**
1. `npm run dev` or `npm run build` executes
2. Automatically runs `generate-css-vars` first
3. CSS variables synchronized
4. Next.js build proceeds
### Standalone Deployment (`start_servers.py`)
```python
def setup_frontend(self):
# Generate CSS variables from colors.mjs before building
self.log("Generating CSS variables from design system...")
result = subprocess.run(
["node", "scripts/generate-css-vars.mjs"],
cwd=str(frontend_dir),
capture_output=True
)
# Then proceed with npm run build
```
---
## Workflow: Changing Colors
**Before (2 files, high risk):**
1. Edit hex in `tailwind.config.ts` line 42
2. Edit hex in `globals.css` line 26
3. Risk: Forget one file, colors diverge
4. Build has no validation
**After (1 file, zero risk):**
1. Edit `colors.mjs` (one location)
2. Run `npm run build`
3. Script auto-generates both Tailwind colors and CSS variables
4. No manual sync needed
**Example:**
```javascript
// colors.mjs
export const colors = {
primary: {
DEFAULT: "#ffb781", // ← Change here
// ...
},
};
```
Then:
-`npm run build` auto-generates CSS variables
- ✅ tailwind.config.ts already imports from colors.mjs
- ✅ Both systems use exact same value
- ✅ Zero inconsistency
---
## CSS Variable Categories
Generated variables are organized by category in `:root`:
```css
/* Base colors from DESIGN.md */
--background: #131313;
--on-background: #e5e2e1;
/* Surface colors from DESIGN.md */
--surface-DEFAULT: #131313;
--surface-dim: #131313;
/* ... 8 more surface variants */
/* Primary colors from DESIGN.md */
--primary-DEFAULT: #ffb781;
--primary-container: #f58618;
/* ... 7 more primary variants */
/* Secondary, Tertiary, Error colors... */
/* Semantic spacing tokens */
--spacing-unit: 4px;
--spacing-gutter: 16px;
/* ... more spacing */
```
---
## Design System Compliance
All colors from `DESIGN.md` are now represented:
| Category | Count | Source |
|----------|-------|--------|
| Primary variants | 9 | colors.mjs |
| Secondary variants | 8 | colors.mjs |
| Tertiary variants | 8 | colors.mjs |
| Surface variants | 9 | colors.mjs |
| Error variants | 4 | colors.mjs |
| Outline/Inverse/Semantic | 7 | colors.mjs |
| **Total** | **45** | **Single file** |
---
## Build Verification
```
✅ CSS generation: Completes successfully
✅ Next.js compile: 5.7s with 0 errors
✅ CSS validation: 0 warnings
✅ TypeScript: Strict mode, 0 issues
✅ All pages: 8/8 generated
```
---
## Future Maintenance
**If colors need updating:**
1. Edit `frontend/colors.mjs`
2. Run `npm run build` (auto-syncs everything)
3. Done!
**No need to:**
- Edit tailwind.config.ts
- Edit globals.css
- Manually synchronize values
- Worry about inconsistency

# Design: Typography & Visual Hierarchy Overhaul
Generated by /gstack-office-hours on 2026-04-19
Branch: dev
Repo: tfm_ainventory
Status: DRAFT
Mode: Builder (Intrapreneurship)
## Problem Statement
The current UI has weak visual hierarchy on tablets and larger screens. While fonts are technically readable, they don't guide the eye — secondary info competes with primary info for attention. Users are forced to hunt for the information they need rather than seeing it immediately.
**Example:** Inventory item name (what you're looking for) is `text-base md:text-lg` (18px). The category label next to it is almost the same size. Which is more important? The UI doesn't say.
## Current State
**Typography scale (Tailwind defaults):**
- Labels/metadata: `text-xs` to `text-base` (1216px)
- Headings: `text-lg` to `text-xl` (1820px)
- Values/highlights: `text-2xl` to `text-3xl` (2430px)
- Page titles: `text-3xl` to `text-4xl` (3036px)
**Problem:** This scale flattens on tablets. A 18px label looks like a headline. A 30px value looks like a label. The hierarchy collapses.
## Premises
1. **Font size alone doesn't create hierarchy.** Weight, color, spacing, and contrast matter more than raw pixels.
2. **Tablet is a first-class device.** The app is used on iPads in warehouses. Design for that, not just mobile.
3. **Visual hierarchy = faster task completion.** If the user sees the item quantity immediately, they spend 0.5 seconds scanning. If they hunt, it's 3 seconds per item. Over 100 items, that's 4 minutes lost per session.
4. **We don't need bigger type everywhere.** Secondary info can stay small IF it's visually subordinate (lighter weight, muted color, less prominence).
## Open Questions
- What's the primary use case breakdown? Mostly mobile in the field, mostly tablet in warehouse, or mixed 50/50?
- Do users ever need to scan and read fine details simultaneously (e.g., zoom control labels)?
- Is there a standard tablet size we're optimizing for (iPad 10.2", iPad Pro 12.9", or both)?
## Approaches Considered
### Approach A: Scale Everything Proportionally (Simplest)
**Summary:** Increase base font sizes across all Tailwind scales uniformly. `text-base``text-lg`, `text-lg``text-xl`, etc. On tablets, everything gets bigger, hierarchy stays the same.
**Effort:** S (one config change to tailwind.config.ts, maybe 15 min)
**Risk:** Low
**Pros:**
- One-line fix in Tailwind config
- Consistent everywhere
- Easiest to test and verify
- No refactoring needed
**Cons:**
- Doesn't actually improve hierarchy — just makes things bigger
- Wasteful on mobile (text gets huge, less content per screen)
- Doesn't address the real problem: weak contrast between important and unimportant info
- Secondary info still competes for attention, just in a bigger font
**Reuses:** Tailwind's built-in scale
**Implementation:** Extend `fontSize` in tailwind.config.ts:
```javascript
extend: {
fontSize: {
'xs': '14px', // was 12px
'sm': '15px', // was 14px
'base': '18px', // was 16px
'lg': '21px', // was 18px
// ... etc
}
}
```
---
### Approach B: Responsive Scale + Weight-Based Hierarchy (Recommended)
**Summary:** Keep mobile readable, boost tablet sizes moderately. More importantly, use **font weight** (not just size) to create hierarchy. Primary info is bold/heavy; secondary is regular/light. Add color emphasis (primary color for key values).
**Effort:** M (audit components for hierarchy, add weight/color rules, test on device, ~2 hours)
**Risk:** Medium (changes visual feel, needs design review)
**Pros:**
- Mobile stays readable (no bloat)
- Tablets get 20-30% bigger type
- Weight creates REAL hierarchy instantly (user's eye goes to bold text)
- Pairs with color (key values in primary color, metadata in muted gray)
- Feels intentional, not lazy
- Works across all screen sizes
**Cons:**
- Requires auditing every component (20+ files)
- Needs design review to ensure consistency
- More moving parts to get right
- Testing on actual tablets essential
**Reuses:** Tailwind's weight classes, existing color system
**Implementation Pattern:**
```jsx
// OLD: No hierarchy
<span className="text-lg text-secondary">Item Name</span>
<span className="text-lg text-muted">Category</span>
// NEW: Clear hierarchy
<span className="text-lg md:text-xl font-bold text-white">Item Name</span>
<span className="text-sm md:text-base font-normal text-muted">Category</span>
```
**Tablet-specific rules:** Add responsive weights:
```javascript
extend: {
fontSize: {
'sm': ['14px', { lineHeight: '1.5' }],
'base': ['16px', { lineHeight: '1.6' }],
'lg': ['18px', { lineHeight: '1.6' }],
'xl': ['20px', { lineHeight: '1.5' }],
}
}
```
---
### Approach C: Fluid Typography + Dynamic Scaling (Future-proof)
**Summary:** Use CSS custom properties (variables) to scale type fluidly from mobile → tablet → desktop. Type size increases as viewport width increases, without discrete breakpoints. Add hierarchy through weight, spacing, and contrast.
**Effort:** L (requires CSS architecture change, build TypeScript scale generator, test thoroughly, ~4 hours)
**Risk:** High (new tooling, requires testing on 3+ device sizes)
**Pros:**
- Scales beautifully on ALL viewport sizes (not just mobile/md/lg breakpoints)
- Future-proof (works on foldables, 5" phones, 27" displays)
- Hierarchy through weight + color, not just size
- Professional feel (type gets more generous as screen gets bigger)
- One source of truth (single scale definition)
**Cons:**
- Adds build-time complexity (need a script to generate scales)
- CSS custom properties have limited browser support (but fine for modern browsers)
- More moving parts, harder to debug
- Needs comprehensive testing
- Overkill if app is only mobile + tablet
**Reuses:** Tailwind, but adds custom CSS layer
**Implementation idea:**
```css
/* Define fluid scale as CSS variables */
:root {
/* At 375px (mobile), base = 16px. At 1440px (desktop), base = 18px. */
--font-base: clamp(16px, 2.5vw, 18px);
--font-lg: clamp(18px, 3vw, 20px);
--font-xl: clamp(20px, 3.5vw, 24px);
}
/* Use in components */
.text-base { font-size: var(--font-base); }
.text-lg { font-size: var(--font-lg); }
.text-xl { font-size: var(--font-xl); }
```
---
## Recommended Approach: B (Responsive Scale + Weight-Based Hierarchy)
**Why:**
- Solves the real problem (hierarchy, not just size)
- Effort-to-impact ratio is excellent
- Works across all devices without bloat
- Uses tools already in the design system
- Reviewable component-by-component (low risk of breaking things)
**Concrete next step:**
1. Audit InventoryTable, StatCard, LogsTable, Scanner controls for hierarchy
2. Add weight rules: primary data `font-bold`, metadata `font-normal`
3. Add color: primary values in `text-primary` or `text-white`, secondary in `text-muted`
4. Test on iPad (actual device or browser dev tools)
5. Review with user on actual tablet to verify readability
---
## Success Criteria
- **Tablet test (10.2" iPad):** User can read item names, quantities, and key metadata without squinting at normal viewing distance (12-18 inches)
- **Hierarchy test:** In a list of 20 items, user can identify which is the primary info (name/quantity) in <1 second without searching
- **Mobile preservation:** iPhone 14 screen still shows useful content (no excessive whitespace)
- **Consistency:** Same typography rules applied across Scanner, Inventory, Admin, Logs pages
---
## Distribution Plan
No new dependencies or build system changes (unless Approach C chosen).
Changes ship in the existing `dev` branch → `master` on next release.
---
## Dependencies
- Tailwind CSS (already in use)
- Design review from user on tablet device (essential)
- Testing across: iPhone 12+, iPad 10.2", iPad Pro 12.9" (ideally)
---
## The Assignment
**Before next office hours:**
1. Load the app on an actual tablet (iPad or comparable).
2. Open the Inventory page, Scanner page, and Admin Dashboard.
3. Note 3 specific screens or components where you think hierarchy is weakest (e.g., "StatCard mixes label and value with equal prominence").
4. Bring those examples to the next session — we'll design the weight/color fixes together with visual mockups.
This turns abstract ("fonts are small") into concrete ("here's where I get lost").
---
## What I Noticed About How You Think
- You didn't say "make fonts bigger" — you said "better visual hierarchy." That's a designer's instinct, not an engineer's kneejerk response. You're thinking about information clarity, not pixel counts.
- You identified the problem on tablets specifically, not mobile. That's precise observation. Most people would have said "everywhere," but you know your actual use case.
- When asked what success looks like, you said hierarchy, not size. That shows you understand that **hierarchy IS the usability feature.** Big text that's all the same weight is just... big, hard-to-read text.
You're thinking like a product person. Keep that going.

# Design System Color Rules - MANDATORY FOR ALL UI/UX
**Status:** ACTIVE | **Effective:** 2026-04-25
**Owner:** AI Development Team | **Audience:** All Frontend Developers/AI Agents
> ⚠️ **CRITICAL RULE:** No hardcoded Tailwind colors are permitted. All UI colors MUST come from `DESIGN.md` color system via tailwind.config.ts or globals.css.
---
## THE RULE
**NEVER use arbitrary Tailwind colors like:**
-`bg-green-500`, `text-green-400`
-`bg-red-600`, `text-rose-500`
-`bg-blue-500`, `text-indigo-400`
-`bg-amber-500`, `bg-yellow-400`
-`bg-sky-500`, `text-cyan-400`
- ❌ Any other standard Tailwind color names
**ALWAYS use semantic colors from DESIGN.md:**
-`bg-primary`, `text-primary`
-`bg-secondary`, `text-secondary`
-`bg-tertiary`, `text-tertiary` (for success/healthy states)
-`bg-error`, `text-error`
-`bg-success`, `text-success`
-`bg-warning`, `text-warning`
-`bg-muted`, `text-muted`
-`border-outline`, `border-outline-variant`
---
## SEMANTIC COLOR MAPPING
Use these mappings for ALL UI decisions:
### **Status Indicators**
| Intent | Color | Value | Use Case |
|--------|-------|-------|----------|
| ✅ Success / Healthy | `tertiary` | #00e639 | "Scanner Ready", quantity +, check-in, online status |
| ❌ Error / Destructive | `error` | #ffb4ab | "Delete item", errors, low stock, offline |
| ⚠️ Warning / Caution | `primary` | #ffb781 | "Caution Orange", warnings, important actions |
| Info / Secondary | `secondary` | #c8c6c5 | Secondary actions, hints, disabled text |
| 🔇 Muted / Disabled | `muted` | #474746 | Disabled buttons, placeholder text |
### **Action Elements**
| Element | Color | Example |
|---------|-------|---------|
| Primary Button | `bg-primary` | "Extract Data", "Create", "Upload" |
| Secondary Button | `bg-secondary` | "Cancel", alternative actions |
| Destructive Button | `bg-error` | "Delete Item", "Discard", "Remove" |
| Button Hover | `hover:opacity-80` | Darken any button on hover |
| Button Focus Ring | `focus:ring-{color}` | Use same color as button |
### **Data Visualization**
| Data Type | Color | Context |
|-----------|-------|---------|
| Quantity Increased | `text-tertiary` | Stock added, items received |
| Quantity Decreased | `text-error` | Stock removed, items shipped |
| Neutral Change | `text-primary/50` | Muted primary |
| Negative Status | `text-error` | Low stock, missing items |
| Positive Status | `text-tertiary` | Available, in stock |
### **Action Log Colors**
| Action Type | Color | Rationale |
|------------|-------|-----------|
| CHECK_IN (receive) | `tertiary` | Success/positive action |
| DELETE | `error` | Destructive action |
| TRASH/DISCARD | `error` | Destructive action |
| CREATE | `primary` | Primary/caution action |
| DB (database) | `secondary` | System/info action |
| REMOVE | `primary` | Warning/caution |
---
## TECHNICAL IMPLEMENTATION
### ✅ CORRECT Examples
```tsx
// Status indicator - success
<div className="w-2 h-2 bg-tertiary animate-pulse" />
<span className="text-tertiary">Scanner: Ready</span>
// Destructive button
<button className="bg-error hover:opacity-80 focus:ring-error">
Delete Item
</button>
// Data change - quantity increased
<span className={log.quantity_change > 0 ? "text-tertiary" : "text-error"}>
{log.quantity_change}
</span>
// Conditional logic using design system
className={`
${item.quantity <= minQty ? "text-error" : "text-primary"}
${isOnline ? "bg-tertiary" : "bg-error"}
focus:ring-${isDestructive ? "error" : "primary"}
`}
// From globals.css variables
const statusColor = {
"success": "var(--tertiary)",
"error": "var(--error)",
"warning": "var(--primary)"
}
```
### ❌ WRONG Examples (DO NOT USE)
```tsx
// ❌ Hardcoded arbitrary colors
<div className="w-2 h-2 bg-green-500 animate-pulse" />
<button className="bg-red-600 hover:bg-red-700">Delete</button>
// ❌ Arbitrary Tailwind color names
className="text-amber-500 bg-indigo-500/10 border border-rose-500/20"
// ❌ Hex colors in className
className="bg-[#4b0082] text-[#ff6b6b]"
// ❌ Mixing design system with arbitrary colors
className="bg-primary hover:bg-green-500 text-error"
```

## COLOR AVAILABILITY IN TAILWIND
All DESIGN.md colors are available in `tailwind.config.ts`:
```typescript
// frontend/tailwind.config.ts - ALREADY CONFIGURED
colors: {
primary: { DEFAULT: "#ffb781", foreground: "#4e2600", ... },
secondary: { DEFAULT: "#c8c6c5", foreground: "#303030", ... },
tertiary: { DEFAULT: "#00e639", foreground: "#003907", ... },
error: { DEFAULT: "#ffb4ab", foreground: "#690005", ... },
success: { DEFAULT: "#00e639", foreground: "#003907" },
warning: "#ffb781",
muted: { DEFAULT: "#474746", foreground: "#a48c7c" },
outline: "#a48c7c",
"outline-variant": "#564335",
// ... all surface, border, background colors
}
```

## CSS VARIABLES (globals.css)
For custom CSS or dynamic color assignment:
```css
/* All available in :root */
--primary: #ffb781;
--secondary: #c8c6c5;
--tertiary: #00e639;
--error: #ffb4ab;
--on-error: #690005;
--error-container: #93000a;
--on-error-container: #ffdad6;
--muted: #474746;
--outline: #a48c7c;
--outline-variant: #564335;
/* ... 50+ more */
```
```tsx
// Usage in React
const statusColor = `var(--${isError ? 'error' : 'tertiary'})`
<div style={{ color: statusColor }} />
```

## ENFORCEMENT RULES FOR AI AGENTS
**BEFORE writing any color-related code:**
1.**Check DESIGN.md** for the semantic intent
2.**Map intent to color** using the Semantic Color Mapping table above
3.**Use design system color** from tailwind.config.ts
4.**Reference this file** if uncertain about color choice
5.**Never** use `bg-green`, `text-red`, `border-blue`, etc.
**During code review:**
- ❌ Flag any hardcoded Tailwind colors (green-*, red-*, blue-*, etc.)
- ✅ Require fixes before merge
---
## 🔒 MANDATORY: All Color Definition Changes → `frontend/colors.mjs` ONLY
**SINGLE SOURCE OF TRUTH RULE (Updated 2026-04-25):**
When adding, updating, or modifying ANY color from DESIGN.md:
### ✅ CORRECT WORKFLOW:
1. Edit ONLY: `frontend/colors.mjs` (the authoritative color source)
2. Update the color definition in the `colors` export object
3. Run: `npm run build` or `npm run dev`
4. Build script AUTOMATICALLY:
- Generates CSS variables in `globals.css` `:root`
- Syncs with `tailwind.config.ts` (which imports from colors.mjs)
- Zero manual sync required
### ❌ INCORRECT WORKFLOWS (DO NOT DO):
- ❌ Editing `tailwind.config.ts` color definitions directly
- ❌ Manually adding CSS variables to `globals.css`
- ❌ Updating colors in multiple files
- ❌ Assuming changes in one file will propagate to another
### Why This Matters:
| Before | After (colors.mjs SSOT) |
|--------|------------------------|
| 2 files to edit | 1 file (colors.mjs) |
| High sync risk | Zero sync risk |
| Manual duplication | Auto-generated |
| Easy to break | Build validates |
### Example: Adding a New Color Variant
```javascript
// ✅ CORRECT: Edit frontend/colors.mjs ONLY
export const colors = {
primary: {
DEFAULT: "#ffb781",
// ← Add new variant here
"subtle": "#f5c5a3", // ← NEW
},
};
// Then: npm run build
// Result: Automatic sync to all systems
```
### Reference Documentation:
- **CLAUDE.md** — Mandatory rule entry point
- **COLOR_SYSTEM_ARCHITECTURE.md** — Technical implementation details
- **colors.mjs** — The authoritative source (keep comments updated)
- ✅ Reference DESIGN_COLOR_RULES.md in comments
**For TypeScript/Linting:**
Add to `.eslintrc.json` if possible:
```json
{
"rules": {
"no-restricted-syntax": [
"error",
{
"selector": "CallExpression[callee.name='className'][arguments.0.value=/bg-(green|red|blue|amber|sky|rose|indigo|emerald|cyan|purple|pink)/]",
"message": "Use DESIGN.md colors (primary, secondary, tertiary, error) instead of arbitrary Tailwind colors"
}
]
}
}
```
---
## EXCEPTION CASES (VERY RARE)
**Only use arbitrary colors for:**
1. **Third-party libraries** (e.g., vitest UI, dev tools) - in node_modules only
2. **Debug/Development tools** - prefixed with `// debug-only`
3. **Dynamic user themes** - explicitly documented with reason
**If you encounter a design need NOT covered by DESIGN.md colors:**
- ❌ Do NOT use arbitrary Tailwind colors
- ✅ Request new color be added to DESIGN.md
- ✅ Create GitHub issue with screenshot and use case
- ✅ Await approval before implementing

## CHECKLIST FOR NEW FEATURES
Before writing UI code, answer:
- [ ] Have I read DESIGN.md colors section?
- [ ] Have I reviewed the Semantic Color Mapping in this file?
- [ ] Have I identified the intent: success/error/warning/info?
- [ ] Have I used the correct semantic color from design system?
- [ ] Have I avoided ALL arbitrary Tailwind colors (green-*, red-*, etc.)?
- [ ] Have I tested the color contrast meets WCAG AA (7:1 ratio)?
- [ ] Have I verified the color looks correct on both light and dark surfaces?

## QUICK REFERENCE
**If you need to color something:**
```
Status = Success/Healthy? → Use tertiary (#00e639)
Status = Error/Failed? → Use error (#ffb4ab)
Action = Warning/Caution? → Use primary (#ffb781)
Action = Secondary/Info? → Use secondary (#c8c6c5)
Text = Muted/Disabled? → Use muted (#474746)
Border = Regular? → Use outline (#a48c7c)
Border = Subtle variant? → Use outline-variant (#564335)
Data change = Increase/Positive? → Use tertiary
Data change = Decrease/Negative? → Use error
```
