Phase 4: Visual Polish

4.1 Font Stack Upgrade:
- Add --font-display token for headings
- Replace all hardcoded font-family: monospace with var(--font-mono)
- Replace hardcoded 'Segoe UI' stack with var(--font-body)

4.2 Shadow Elevation System:
- Add --shadow-2xl, --shadow-card/dropdown/modal/toast/header/dark-lg tokens
- Replace hardcoded shadows in header, menu, banner, shared, recipe-modal,
  progress-panel, import-modal, alphabet-bar with semantic tokens
- Add dark theme shadow overrides with increased opacity

4.3 Transitions & Micro-interactions:
- Replace transition: all with specified properties (performance)
- Use --transition-fast/base/slow tokens instead of hardcoded 0.2s/0.3s
- Add :active scale feedback to modal buttons
- Enhance card hover with box-shadow + border-color lift

4.4 Dark Theme Refinement:
- Elevated shadow opacity for dark theme visibility

4.5 Density:
- Standardize container padding with --space-2 token
