- touch-action is per-element, not inherited. Setting `pan-x pan-y` on
html/body alone didn't stop the kanban board: pinching on `.board`
reads `.board`'s own touch-action (auto by default), which permits
pinch-zoom. Switch to `* { touch-action: pan-x pan-y }` inside the
mobile media query so every element opts out of pinch by default;
element-specific overrides (touch-action: none on resize handles,
drag-source rules on TaskCard, etc.) still win on specificity.
- Add `overscroll-behavior: none` to html/body to prevent Chrome's
rubber-band scroll, which was letting users pull the page up to
expose empty space above the dashboard despite overflow:hidden.
