## Design Philosophy

Vesper was designed with these principles in mind:

1. **Content First** - The reader is the primary focus. All UI elements can be hidden.
2. **Typography Matters** - Reading should be comfortable. We use Inter with carefully tuned line heights (1.7), optimal line width (~65 characters), and generous whitespace.
3. **Dark by Default** - The deep onyx base color (#282C33) reduces eye strain and looks professional.
4. **Keyboard Driven** - Power users can do everything with keyboard shortcuts.
5. **Minimalist Chrome** - The interface gets out of your way.
