   The page shell, and the scrolling rule
   --------------------------------------------------------------------------
   Layout budget: the desktop window is 680 x 850, which leaves roughly
   640 x 630 of usable content. Every screen is designed to fit that without
   scrolling, and where content genuinely overflows, ONE inner region scrolls —
   never the page, and never two regions at once.

   So .main does not scroll. A view builds a .page: a fixed .page-head, one
   .page-scroll that takes the remaining height, and a fixed .page-foot holding
   the primary action. That is what keeps Send on screen.

   Everybody in the practice is listed down the left, so starting a

   The rail and the history scroll independently. That is two scrolling areas,

   another. These are siblings, and the composer never moves.
