/* ───────── Modes — a guided product demo ─────────
   Calm (no JS / reduced motion): the head, then per mode a chapter header and
   its steps, each a still window in its end state with the story beside it. Pinned: one app window beside its story; modes.js plays
   a cursor clip per mode (typing, clicks, mode switch) and ticks the story's steps. Window, bodies and veil share one box (--bl/--bt/--bs,
   design size --dw × --dh) that modes.js fits to the stage. */
