## 📋 Font Application Hierarchy
### 1. CSS Custom Properties (Highest Priority)
```css
:root {
--font-heading: 'Inter', sans-serif;
--font-body: 'Inter', sans-serif;
}
```
### 2. Global CSS Rules
```css
/* 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
```typescript
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.

**Solution**:
1. Check if `chakra-ui-dark` class is on body
2. Verify color values in AdminLayout
3. Clear localStorage and try again
4. Check CSS order in index.tsx
### Database Migration

**Solution**:
```bash
# Run migration
make migrate-up
# Or manually
goose -dir database/migrations postgres "connection-string" up
```

## 📊 Performance Impact
### Font Loading
- **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)
