/* ---------- Motion hygiene note ----------
   Every transition above names explicit properties (transform, opacity, color,
   background-color, border-color, filter) — never `all`, and never a property
   that triggers layout. tests/static-checks.mjs enforces that list.
   Entrances never start at scale(0); pressables use :active { transform: scale(.97) }.
