/* docs/offline-pwa.md R-C15 — the PAGE must never scroll.
   The product is a fixed frame: header, a named scroll region, footer. If the
   document scrolls too, the header scrolls away, the version chip drifts, and
   a drag that reaches the end of the inner region chains out to the page and
   drags the whole board under the player's thumb. That is the "double scroll".
   `overflow: hidden` stops the second scrollbar; `overscroll-behavior: none`
   stops the chaining, which is the half that is invisible on a desktop mouse
   and obvious on a phone. */
