📋 Font Application Hierarchy

1. CSS Custom Properties (Highest Priority)

:root {
  --font-heading: 'Inter', sans-serif;
  --font-body: 'Inter', sans-serif;
}

2. Global CSS Rules

/* All elements inherit body font */
*, html, body {
  font-family: var(--font-body, ...fallbacks);
}

/* All headings use heading font */
h1, h2, h3, h4, h5, h6 {
  font-family: var(--font-heading, ...fallbacks) !important;
}

3. Chakra UI Theme

theme: {
  fonts: {
    heading: 'var(--font-heading, ...)',
    body: 'var(--font-body, ...)'
  }
}

4. Component-Specific Overrides

Admin components have additional font rules to ensure consistency in the admin panel.

🐛 Troubleshooting

Fonts Not Applying

Issue: Fonts don't change after selection Solution:

Clear browser cache
Refresh page (Ctrl+F5)
Check browser console for errors
Verify Google Fonts are loading (Network tab)

Dark Mode Issues

Issue: Dark mode colors look wrong Solution:

Check if chakra-ui-dark class is on body
Verify color values in AdminLayout
Clear localStorage and try again
Check CSS order in index.tsx

Database Migration

Issue: Font fields not in database Solution:

# Run migration
make migrate-up

# Or manually
goose -dir database/migrations postgres "connection-string" up

📊 Performance Impact

Fonts cached by browser after first load
Non-blocking load using Google Fonts CDN
Fallback fonts ensure content is always readable
font-display: swap prevents FOIT (Flash of Invisible Text)

CSS File Sizes

admin-enhancements.css: ~25KB
global-enhancements.css: ~15KB
Total overhead: ~40KB (minified and gzipped: ~8KB)
