/* Nested scroll areas (lists, code, dropdowns, wide tables, tab rows) keep the wheel/finger to themselves at their ends
   only while they really overflow: a scroll-driven animation is active only on a scrollable box, so a short box still
   lets the page scroll. !important keeps it under prefers-reduced-motion (it moves nothing). Browsers without scroll
   timelines fall back to normal chaining. Feature stylesheets add their own boxes with the same two declarations. */
