/* The comparison as two chat windows (2026-09-02; restyled the same day on
   John's review: it has to read as a real messaging window at a glance).
   The windows sit inside the demo app-window exception (rounded window,
   soft shadow, chat bubbles, a composer), the way the sample suite draws
   Outlook and Teams; the page around them stays on the paper rules. The
   memory window's avatar is the view's one signal mark. */
