   EXPERT STAGE CLEARED  (core/stage-clear.js)

   Lutfi's "Quantum Dawn Stage Cleared" design, as a look for the Expert's
   "stage" sheet. The design's own sizes and its short-screen, 850 px and
   620 px layouts are kept; a phone held sideways gets a compact card with
   no celebration panel, so the numbers, the next stage and the buttons
   are all on one screen. Only the middle scrolls; the buttons stay put.
   Every rule starts .sheet-clear .qsc (the plain sheet's class names on
   the buttons are hooks only).
