/* ───────── Apps — one conversation across many apps ─────────
   Calm (no JS / reduced motion): the beat statements, the example request
   with its three results, then the two groups (built in, add-ons) as tile
   grids. Pinned: one stage, three beats. apps.js gives every tile, label,
   result and the chain line its place per beat (--x/--y in em from the stage
   centre, --s scale, --o opacity) and CSS glides between them; within the
   middle beat it types the request and lands the results one by one.
   App marks are the makers' own, unmodified, on light icon tiles. */
