/* ── The shell every activity in the suite wears ───────────────────────
   Built for a Promethean panel: a five-year-old is about 43 inches tall and
   works comfortably below about 48, so everything they touch sits in the
   lower half of the glass. The number lives up top where the whole room
   reads it and nobody needs to reach it. Targets are palm-sized and drop
   zones snap generously, because aim at arm's length on glass is about an
   inch. */
