Executive Summary

Category	Score	Status
Design Tokens	95%	Good
Dark Mode	90%	Good
Accessibility	70%	Fair
Performance	85%	Good
Maintainability	80%	Good
Overall Score	84%	Good

Strengths

• Consistent and well-documented OKLCH design token system
• Well-defined hybrid Tailwind/Scoped styles architecture
• Complete dark mode support on most components
• Consistent use of CSS custom properties
• Well-implemented data-variant/data-size pattern

Areas for Improvement

• Missing prefers-reduced-motion support (accessibility)
• Some hardcoded values (white instead of tokens)
• Missing focus states on some interactive components
• Duplicate .sr-only class across multiple components

Current Metrics

File Distribution

Metric	Value	Percentage
Total Svelte files	88	100%
Files with <style>	26	30%
Tailwind-only files	62	70%
Files with :global()	22	25%
Files with inline styles	6	7%

Design System

Metric	Value
CSS variables	~70
Color palettes	18
Font pairings	30
Utility classes	15

CSS Bundle Size (Production)

File	Size	Gzip
0.CIcGkYdh.css (layout)	59.79 kB	9.43 kB
3.BJGE_YKl.css (theme page)	175.59 kB	26.60 kB
ConsentStatusCard.D4C9130X.css	38.39 kB	5.47 kB
Estimated total	~274 kB	~42 kB

Note: The theme file (175 kB) is large because it contains all 18 palettes and 30 fonts. This CSS is only loaded on /theme.

Compliance Analysis

1. Design Tokens

Criterion	Status	Notes
Colors via CSS custom props	✅	Well implemented
Spacing via tokens	✅	--spacing-* used
Typography via tokens	✅	--text-*, --font-*
Border radius via tokens	✅	--radius-*
Transitions via tokens	✅	--transition-*
Shadows via tokens	✅	--shadow-*

2. data-variant/data-size Patterns

Components using data-variant (12):

• Alert.svelte ✅
• Badge.svelte ✅
• InfoCard.svelte ✅
• StatCard.svelte ✅
• LinkButton.svelte ✅
• LoadingSpinner.svelte ✅
• Section.svelte ✅
• CenteredLayout.svelte ✅
• PageLayout.svelte ✅
• PageHeader.svelte ✅
• KeyValue.svelte ✅
• ErrorState.svelte ✅

Components using data-size (5):

• Badge.svelte ✅
• StatCard.svelte ✅
• LinkButton.svelte ✅
• LoadingSpinner.svelte ✅
• KeyValue.svelte ✅

3. Dark Mode

Criterion	Status	Notes
:global(.dark) pattern used	✅	22 files
Colors adapted correctly	✅	Light/Dark consistent
Smooth transitions	✅	transition-colors applied
OKLCH for preserved tints	✅	Used in Badge, Alert

4. Accessibility

Criterion	Status	Notes
Visible focus states	⚠️	Present on 2/26 components
prefers-reduced-motion	❌	Not implemented
Screen reader support (.sr-only)	⚠️	Duplicated, needs centralization
WCAG AA contrasts	✅	OKLCH ensures good contrasts
role attributes	✅	Present where needed

5. Performance

Criterion	Status	Notes
PurgeCSS active (Tailwind)	✅	v4 integrated
No CSS-in-JS runtime	✅	Static CSS
CSS code splitting	✅	Per route
GPU-accelerated animations	✅	transform used

Identified Issues

High Priority

P1: Missing prefers-reduced-motion

Affected files: All components with animations

Impact: Accessibility - users sensitive to motion

Recommendation: Add to app.css:

@media (prefers-reduced-motion: reduce) {
	*,
	*::before,
	*::after {
		animation-duration: 0.01ms !important;
		animation-iteration-count: 1 !important;
		transition-duration: 0.01ms !important;
		scroll-behavior: auto !important;
	}
}

P2: Missing focus states

Affected files:

• Button.svelte - Minimal focus state
• DataTable.svelte - No focus on rows
• Badge.svelte - No focus (non-interactive, OK)
• Several interactive components

Impact: Difficult keyboard navigation

Recommendation: Add :focus-visible to all interactive elements

Medium Priority

P3: Hardcoded white value

Affected files:

• DataTable.svelte:153 - background-color: white
• DataTable.svelte:208 - background-color: white
• StatCard.svelte:89 - --stat-bg: white
• LinkButton.svelte:117 - --btn-text: white

Impact: Potential inconsistency with design system

Recommendation: Replace with var(--color-secondary-50) or create a --color-surface token

P4: Duplicate .sr-only

Affected files:

• LoadingSpinner.svelte:98-108
• DataTable.svelte:272-282

Impact: Duplicate code, difficult maintenance

Recommendation: Add .sr-only as utility class in app.css

Low Priority

P5: Dynamic inline styles

Affected files (6):

• ColorSwatch.svelte - Justified (dynamic colors)
• ColorScaleRow.svelte - Justified (dynamic colors)
• HealthStatusCard.svelte - To evaluate
• Modal.svelte - Dynamic width
• Signup.svelte - To evaluate
• theme/+page.svelte - Justified (preview)

Impact: Low, most are justified

Recommendation: Review HealthStatusCard.svelte and Signup.svelte

P6: Animation without will-change

Affected files:

• Button.svelte - spinner animation
• LoadingSpinner.svelte - spin animation

Impact: Potentially non-optimal performance

Recommendation: Add will-change: transform to animated elements

Recommendations

Short Term (Current Sprint)

1. Add prefers-reduced-motion in app.css
2. Add global .sr-only in app.css @layer utilities
3. Audit focus states of interactive components

Medium Term (Next Sprint)

4. Replace hardcoded white with tokens
5. Create a --color-surface token for card backgrounds
6. Document naming conventions for local CSS custom properties

Long Term (Backlog)

7. Evaluate adding Stylelint to automate checks
8. Create visual tests with Playwright for UI components
9. CSS performance benchmark with Lighthouse
