   Responsive — 4 breakpoints following a mobile-first approach.
   Key principles (learned from ComprehensiveKenyaSafaris):
   - 2-column grids on phones where possible to reduce scroll debt
   - min-height 44px on tap targets, 48px on form inputs
   - font-size 16px on inputs (prevents iOS auto-zoom)
   - tighter section padding on small screens
