   MOBILE SCROLL RESTORATION (must come LAST)
   The desktop `body.noc { height: 100vh; overflow: hidden }` rules above
   appear AFTER the main mobile media block, so source order makes them
   win on mobile too — that pinned the dashboard at viewport height with
   no overflow, killing scroll. This block re-asserts the mobile scroll
   model after those rules so it wins by source order.

   Scroll model: BODY is the only scroll container. `.main` and `.content`

   Safari to freeze momentum scrolling.
