- H3: 20px / 1.4 line height (Subsection headings)
- H4: 16px / 1.5 line height (Minor headings)
- Body: 14px / 1.6 line height (Content text)
- Small: 12px / 1.5 line height (Captions, labels)

Weight Distribution:
- Regular (400): Body text, descriptions
- Medium (500): Form labels, smaller headings
- Semibold (600): Section headings, emphasis
- Bold (700): Page titles, strong emphasis

Issues Found:
⚠️ H4 (16px) used inconsistently (sometimes 14px)
⚠️ Line height too tight in some places (1.2 < 1.4 minimum for accessibility)
✅ Good contrast between weights
\`\`\`

#### Spacing System
\`\`\`
Base Unit: 4px (0.25rem)
Scale: 4px, 8px, 12px, 16px, 24px, 32px, 48px, 64px

Usage Consistency:
- Page padding: Consistent (24px on desktop, 16px on mobile)
- Component spacing: Mostly consistent (8px/16px between components)
- Internal component padding: Variable (4px-16px inside components)

Issues:
⚠️ Inconsistent padding inside cards (ranging 12px-20px)
✅ Margin between sections consistent (24px-32px)
\`\`\`
```

### Phase 3: Interaction Patterns Analysis (10 minutes)

**Purpose**: Analyze interactions, forms, modals, and navigation.

#### Interaction Detection

```bash
grep -r "onClick\|onChange\|onSubmit\|onHover" src/ | wc -l
grep -r "modal\|dialog\|popover\|tooltip\|dropdown\|menu" src/ -i
grep -r "form\|input\|submit\|validation" src/components/
```

#### Interactions Documentation

```markdown
### User Interactions

#### Form Patterns
\`\`\`
Form Types Implemented:
1. Login Form (Single column, 2 fields, 1 submit button)
   - Fields: Email, Password
   - Validation: Real-time
   - Error handling: Inline messages
   - Submission: API call with error/success feedback

2. Registration Form (Multi-step, 3 steps)
   - Step 1: Basic info (name, email)
   - Step 2: Password, confirm password
   - Step 3: Profile picture, bio
   - Validation: Step-by-step validation
   - Progress: Visual step indicator

3. Product Filter Form (Sidebar, multiple controls)
   - Controls: Category select, price range slider, rating
   - Behavior: Live filtering on change
   - Mobile: Collapsible on small screens

4. Checkout Form (Single page, 3 sections)
   - Shipping info
   - Billing info (copyable from shipping)
   - Payment info
   - Validation: Field-level validation
   - Submission: Multi-step with confirmation

Issues Found:
⚠️ No loading states on form submit in 3 forms
⚠️ Error messages not dismissible in one form
✅ Success feedback clear and visible
\`\`\`

#### Modal/Dialog Patterns
\`\`\`
Modals Implemented:
1. Confirmation Dialog (Delete product)
   - Buttons: Cancel, Delete (danger)
   - Animation: Fade in/out
   - Accessibility: Focus trapped, escape closes

2. Form Modal (Add to wishlist)
   - Content: Form with submit/cancel
   - Size: Small (400px max-width)
   - Animation: Slide up on mobile

3. Image Gallery Modal (Product images)
   - Navigation: Previous/next buttons
   - Keyboard: Arrow keys supported
   - Close: X button, escape key, click outside

4. Alert Modal (Critical error)
   - Blocking: Cannot close without action
   - Buttons: OK only
   - Styling: Error color theme

Consistency:
✅ All modals have close buttons/actions
✅ Consistent animation timing (200ms)
⚠️ Some inconsistency in button order (Cancel/OK vs OK/Cancel)
\`\`\`

#### Navigation Patterns
\`\`\`
Navigation Types:
1. Main Navigation (Top header)
   - Horizontal menu with logo
   - User menu dropdown (Profile, Settings, Logout)
   - Search bar

2. Sidebar Navigation (Authenticated layout)
   - Vertical menu with icons
   - Collapsible groups
   - Active state highlighting
   - Mobile: Hamburger menu

3. Breadcrumbs (Product pages, admin)
   - Shows current page hierarchy
   - Links to parent pages
   - Current page: Text only (not clickable)

4. Pagination (Lists, tables)
   - Page numbers with current page highlighted
   - Previous/Next buttons
   - Go to page input

5. Tab Navigation (Settings, profile)
   - Horizontal tabs with underline indicator
   - Tab content panel switching
   - Keyboard navigation (arrow keys)

Issues:
⚠️ Breadcrumbs don't appear on some pages
⚠️ Mobile navigation could be improved
✅ Tab navigation accessible
\`\`\`

#### Animation Patterns
\`\`\`
Animations Used:
- Page transitions: Fade (200ms)
- Component enter: Slide up (250ms)
- Component exit: Fade out (150ms)
- Hover effects: Scale/opacity (150ms)
- Loading spinners: Rotation (linear, 1s)

Consistency:
✅ Timing consistent across interactions
✅ Easing consistent (ease-in-out)
⚠️ Some animations feel slower on mobile
\`\`\`

### Phase 4: Responsive Design Assessment (8 minutes)

**Purpose**: Evaluate mobile optimization and responsive design.

#### Responsive Design Analysis

```markdown
### Responsive Design

#### Breakpoints
\`\`\`
Defined Breakpoints:
- Mobile: 0px - 640px (sm)
- Tablet: 641px - 1024px (md)
- Desktop: 1025px+ (lg)

Media Query Usage:
✅ Mobile-first approach
✅ Consistent breakpoint usage
⚠️ No custom breakpoints for specific content

Coverage:
- 95% of components responsive
- 2 components desktop-only (admin tables)
- All pages responsive ✅
\`\`\`

#### Mobile Optimization
\`\`\`
Touch Targets:
✅ Buttons: 44px minimum (44x44 or 48x48)
⚠️ Some icon-only buttons: 36px (small)
✅ Links: 44px minimum

Layout:
✅ Single column layout on mobile
✅ Touch-friendly spacing maintained
⚠️ Some modals too wide on tablet (should be narrower)

Navigation:
✅ Hamburger menu on mobile
✅ Sidebar collapses
⚠️ Top navigation bar could be more compact

Performance on Mobile:
- LCP: 2.1s (target: <2.5s) ✅
- FID: 64ms (target: <100ms) ✅
- CLS: 0.08 (target: <0.1) ✅
\`\`\`
```

### Phase 5: Accessibility Audit (12 minutes)

**Purpose**: Comprehensive WCAG compliance assessment.

#### Accessibility Detection

```bash
grep -r "aria-\|role=\|alt=\|title=" src/ | wc -l
grep -r "h1\|h2\|h3\|h4\|h5\|h6" src/ | wc -l
grep -r "type=\"checkbox\"\|type=\"radio\"\|select" src/ | wc -l
```

#### Accessibility Documentation

```markdown
### Accessibility (WCAG 2.1 AA Compliance)

#### Color Contrast
\`\`\`
WCAG AA Requirements: 4.5:1 for text, 3:1 for graphics

Audit Results:
✅ All text colors: 4.5:1+ contrast
⚠️ Secondary orange (#f59e0b): 4.2:1 on white (below 4.5:1)
   Recommendation: Use #f59e0b on white only for graphics, use darker orange for text

✅ Button contrast: All buttons 4.5:1+
✅ Link contrast: All links 4.5:1+
\`\`\`

#### Semantic HTML
\`\`\`
Proper Usage:
✅ <button> for buttons (not <div onclick>)
✅ <a> for links
✅ <h1> - <h6> for headings
✅ <label> for form inputs
✅ <nav> for navigation
✅ <main> for main content
✅ <article>, <section>, <aside> for content areas

Issues Found:
❌ 3 instances of <div> used as buttons
❌ 2 image buttons missing accessible names
⚠️ Some headings skipped (h2 → h4, should be h2 → h3)
\`\`\`

#### ARIA Implementation
\`\`\`
ARIA Attributes Used:
✅ aria-label: 15 instances (proper usage)
✅ aria-describedby: 8 instances (form error descriptions)
✅ aria-expanded: 6 instances (collapsible menus)
✅ aria-live: 3 instances (alerts, notifications)
✅ role="tablist", role="tab", role="tabpanel": Tab component
✅ aria-current="page": Current navigation item

Missing/Incorrect:
⚠️ Modal dialog missing role="dialog"
⚠️ Dropdown button missing aria-haspopup="listbox"
❌ Custom toggle switch missing proper ARIA

Recommendations:
- Add role="dialog" to modals
- Add aria-haspopup to dropdown triggers
- Add aria-pressed to toggle buttons
\`\`\`

#### Keyboard Navigation
\`\`\`
Keyboard Support:
✅ Tab key navigates through all interactive elements
✅ Enter/Space activates buttons
✅ Arrow keys navigate tabs
✅ Escape closes modals
⚠️ Some dropdown menus not keyboard accessible
❌ Tooltip triggers require hover (not keyboard accessible)

Issues:
- Custom select component: No keyboard support
- Tooltip component: Hover-only, not keyboard accessible
- Custom slider: Partial keyboard support (needs arrow keys)
\`\`\`

#### Screen Reader Testing
\`\`\`
Testing Tool: NVDA, JAWS

Issues Found:
❌ Image buttons missing alt text (3 instances)
❌ Icon-only buttons not announced properly (5 instances)
⚠️ Form instructions not associated with fields (2 forms)
⚠️ Data table headers not properly marked

Working Well:
✅ Navigation structure clear
✅ Form field labels announced
✅ Error messages associated with fields
✅ Page structure logical

Fixes Needed:
- Add alt text to all images and image buttons
- Use aria-label for icon-only buttons
- Associate instructions with aria-describedby
- Mark table headers with <th>
\`\`\`

#### Accessibility Score: WCAG AA - 87%
\`\`\`
✅ Passing (90%+): Color contrast, Semantic HTML
⚠️ Needs Work (70-89%): ARIA usage, Keyboard navigation
❌ Failing (<70%): Screen reader compatibility
\`\`\`

✅ Logical grouping
⚠️ Deep nesting for some admin pages
\`\`\`

#### User Flows
\`\`\`
Critical Flows Analyzed:

1. Product Purchase Flow (Happy Path)
   Browse → Product Detail → Add to Cart → Checkout → Payment → Confirmation
   Friction Points: ⚠️ Checkout form too long (3 sections)

2. User Registration Flow
   Sign Up → Email Verification → Complete Profile → Dashboard
   Friction Points: ⚠️ Multi-step form might lose users

3. Post-Purchase Flow
   Confirmation → Email Receipt → Track Order → Delivery
   Friction Points: ✅ None identified

Error Recovery:
✅ Clear error messages
⚠️ Limited recovery options (missing "Did you mean" suggestions)
\`\`\`

#### Usability Issues
\`\`\`
Identified Issues:

🟠 High Priority (Fix This Sprint):
- 2 CTAs with unclear text ("Submit" vs "Save")
- Search results page lacks filtering options
- Mobile hamburger menu closes on navigation (confusing UX)

🟡 Medium Priority (Fix This Month):
- Breadcrumbs missing from some category pages
- Pagination could show total count
- Error messages could suggest next steps

🟢 Low Priority (Nice-to-Have):
- Loading skeletons could improve perceived performance
- Undo functionality for some destructive actions
\`\`\`
```

### Phase 7: Design Consistency Audit (6 minutes)

**Purpose**: Evaluate consistency of design patterns and components.

#### Consistency Analysis

```markdown
### Design Consistency

#### Component Usage Consistency
\`\`\`
Button Styles:
✅ Consistent variant usage (primary, secondary, danger)
⚠️ One component uses old button style (legacy page)
✅ Sizing consistent (sm, md, lg)

Card Components:
✅ All cards have consistent shadow and border
⚠️ Some cards have padding inconsistency (12px vs 16px)

Form Styling:
✅ Input fields consistent
✅ Label styling consistent
⚠️ Placeholder text color varies between browsers (should be fixed)

Issues:
- 1 outdated button style found on legacy page
- Card padding inconsistency in 3 instances
\`\`\`

#### Visual Hierarchy Consistency
\`\`\`
✅ Primary actions prominent (blue, larger)
✅ Secondary actions clear (gray outline)
✅ Tertiary actions smaller/subtle
⚠️ Some danger actions not clearly distinguished (missing red color)

Typography Hierarchy:
✅ H1 clearly distinguishes page titles
⚠️ H2-H4 sizing not always distinguishable
\`\`\`
```
