- Components: 3 new, 1 to extend
- Breaking Changes: 1 (MetricCard props)

---

## New Design Tokens

### Colors
- **color.status.warning.500**: `#F59E0B` (color)
  _Warning state for metrics below threshold_
- **color.status.error.600**: `#DC2626` (color)
  _Error state for critical metrics_
- **color.status.success.500**: `#10B981` (color)
  _Success state for metrics above target_
- **color.neutral.50**: `#F9FAFB` (color)
  _Card background for dashboard widgets_

### Spacing
- **spacing.section.gap**: `48px` (dimension)
  _Gap between dashboard sections_
- **spacing.widget.padding**: `24px` (dimension)
  _Internal padding for metric widgets_
- **spacing.metric.gap**: `12px` (dimension)
  _Gap between metric label and value_

### Typography
- **typography.heading.xl**: `36px/600/42px` (typography)
  _Large dashboard headings_
- **typography.metric.value**: `48px/700/52px` (typography)
  _Metric display values_
- **typography.metric.label**: `14px/500/20px` (typography)
  _Metric labels_

### Other Tokens
- **radius.widget**: `12px` (dimension)
  _Border radius for dashboard widgets_
- **shadow.widget**: `0 1px 3px rgba(0,0,0,0.1)` (shadow)
  _Subtle shadow for elevated widgets_

## Modified Design Tokens

### color.primary.600
- **Old Value**: `#1D4ED8`
- **New Value**: `#2563EB`
- **Impact**: Affects primary buttons and links throughout dashboard

### spacing.md
- **Old Value**: `16px`
- **New Value**: `20px`
- **Impact**: Increases default spacing in grid layouts

### typography.body.medium
- **Old Value**: `16px/400/24px`
- **New Value**: `16px/500/24px`
- **Impact**: Slightly bolder body text for better readability

## New Components Required

### Atoms (Basic Elements)

#### StatBadge

**Purpose**: Small metric indicator with icon and optional pulse animation
**Variants**: success, warning, error, info
**States**: default, pulse (animated)
**Similar to**: Badge (78% match)

**Recommendation**: Extend existing Badge component with `variant="stat"` prop instead of creating new component. Add icon prop and pulse animation state.

### Molecules (Simple Combinations)

#### TrendIndicator

**Purpose**: Show metric trend with arrow and percentage change
**Composition**: Icon (arrow up/down) + Text (percentage) + StatBadge
**Variants**: up (green), down (red), neutral (gray)
**Similar to**: None (0% match)

**Recommendation**: Create new molecule component. Reuse StatBadge internally.

### Organisms (Complex Components)

#### DashboardGrid

**Purpose**: Responsive grid layout for dashboard widgets
**Composition**: Grid container + flexible widget slots
**Responsive**: 1 col (mobile), 2 col (tablet), 3 col (desktop)
**Similar to**: None (0% match)

**Recommendation**: Create new organism component with responsive grid behavior. Use CSS Grid for layout.

---

## Component Reuse Opportunities

### StatBadge → Extend Badge

**Similarity**: 78%
**Recommendation**: Extend existing Badge component with new variant instead of creating duplicate component
**Time Saved**: 2-3 hours

**Approach**: Add `variant="stat"` option to Badge props. Add `icon` prop for optional icon display. Add `pulse` boolean prop for animation state. Maintains existing Badge API while adding new functionality.

### MetricCard → Enhance Existing

**Similarity**: 85%
**Recommendation**: Add trend and comparison props to existing MetricCard component
**Time Saved**: 2 hours

**Approach**: Add `trend` prop (up/down/neutral). Add `comparisonPeriod` prop (string). Both optional initially for backward compatibility. Mark as required in v3.0.0.

## Design System Impact

### Token Health

- **In Sync**: 87 tokens
- **Drift Detected**: 5 tokens
- **Missing in Code**: 12 tokens
- **Unused in Design**: 3 tokens

**Sync Status**: Drift Detected
**Priority Level**: High

### High Impact Changes

- **Color primary.600 modification**
  - **Impact**: Breaking change for custom theme consumers
  - **Action Required**: Update documentation, notify users in changelog

- **Spacing.md increase** (16px → 20px)
  - **Impact**: Layout shifts in existing grid components
  - **Action Required**: Visual regression testing on all layouts

### Low Impact Changes

- Typography weight increase (400 → 500) - minimal visual change
- New status colors - additive only, no conflicts
- New widget tokens - isolated to dashboard feature

---

## Implementation Recommendations

### Phased Approach

**Phase 1: Design Tokens** (2 hours)
- Priority: High
- Add 12 new tokens to design-tokens.json
- Update 5 existing tokens
- Run Style Dictionary build
- Update Tailwind @theme

**Phase 2: Atomic Components** (3 hours)
- Priority: High
- Extend Badge component with stat variant (2h)
- Add pulse animation to Badge (1h)

**Phase 3: Molecule Components** (2 hours)
- Priority: Medium
- Create TrendIndicator component (2h)

**Phase 4: Organism Components** (5 hours)
- Priority: Medium
- Create DashboardGrid component (3h)
- Enhance MetricCard with trend props (2h)

### Total Estimated Time

**12 hours** (Medium complexity)

## Breaking Changes

### MetricCard

**Issue**: Adding required `trend` and `comparisonPeriod` props breaks existing usage
**Previous Mapping**: `src/components/molecules/MetricCard.tsx` (8 existing usages)
**Recommendation**: Add props as optional first, then require in major version

**Migration Steps**:
- Add props as optional in v2.4.0
- Add deprecation warning when props not provided
- Update all 8 existing usages in codebase
- Document migration in CHANGELOG.md
- Make props required in v3.0.0 (breaking change)
- Provide codemod script for automated migration

## Next Steps

1. **Review Implementation Plan**: `.agent/tasks/TASK-16-dashboard-redesign.md`
2. **Update Design Tokens**: Phase 1 implementation
3. **Implement Components**: Follow atomic design hierarchy
4. **Test & Verify**: Visual regression, accessibility, unit tests
5. **Update UI Kit Inventory**: After each component completion
