Mobile Gesture Support
Touch interactions work correctly and don't conflict with system gestures.
Check
Verify: (1) all tappable elements ≥ 44×44px, (2) horizontal swipe in carousels/drawers doesn't conflict with browser back gesture, (3) no hover-only interactions (hover is unavailable on touch), (4) tap delay eliminated (touch-action: manipulation), (5) scroll areas work with one-finger scroll, (6) pinch-to-zoom not disabled on content pages.
Why This Matters
Mobile gestures have OS-level conventions users expect everywhere. Conflicts between app swipes and browser back gestures are disorienting. Hover-only interactions are completely invisible to touch users — any interaction available on hover must also be available on tap.

How to Verify
Test on a physical device (not just browser DevTools). Use one hand only. Verify all interactions are reachable with thumb, no hover states are required, and scroll areas work without two-finger scroll.
