| 27 | + |
| 28 | +## Technical Details |
| 29 | + |
| 30 | +### CSS Architecture Layers |
| 31 | + |
| 32 | +1. **Foundation Layer** (`globals.css`) |
| 33 | + |
| 34 | + - Sets up Tailwind CSS |
| 35 | + - Defines static fallback values |
| 36 | + - Establishes base CSS variables |
| 37 | + |
| 38 | +2. **Theme Layer** (`theme.css`) |
| 39 | + |
| 40 | + - Maps DaisyUI variables to Shadcn names |
| 41 | + - Handles light/dark mode switching |
| 42 | + - Provides dynamic theme values |
| 43 | + |
| 44 | +3. **Component Layer** |
| 45 | + - Uses variables from both layers |
| 46 | + - Implements component-specific styles |
| 47 | + - Maintains consistent theming |
| 48 | + |
| 49 | +### Variable Naming Strategy |
| 50 | + |
| 51 | +- Clear hierarchy in variable names |
| 52 | +- Consistent prefixing for different types |
| 53 | +- Proper fallback values for each variable |
| 54 | + |
