Subject: [PATCH] style: overhaul design tokens, shadows, animations, and glass
 utilities

- Replace warm/mixed color palette with clean cool blue-grey tokens
- Reduce border-radius from 1.25rem to 0.75rem
- Rewrite shadow system using oklch with proper depth scale
- Switch fonts from custom serif/sans to Geist Sans/Mono CSS vars
- Add CSS animation keyframes (fade-in, slide-up, slide-down, scale-in)
- Add glass, glass-card, and glass-strong utility classes
