   All selectors scoped to [data-design="b"].dq-design or descendants.
   Keyframes prefixed bm- (shared grammar, distinct slot).
   MOTION GATE: animate ONLY transform / opacity / clip-path / stroke-dashoffset.
   ZERO layout/paint prop animations.
   Every :hover/:focus-visible transform inside @media(hover:hover)and(pointer:fine).
   No scale(0) from-nothing (starts at scale(0.92+)).
   No ease-in on entrances.
