 * Client-side reduced-motion floor: an `@media (prefers-reduced-motion: reduce)`
 * block that kills the tween AND settles the boundary at its end pose.
 *
 * Emitted UNCONDITIONALLY when the intent's policy is `reducedMotion: 'settle'`
 * — not only when the compiler was called with a server-side
 * `prefersReducedMotion` hint. The hint path (Sec-CH detection) zeroes durations
 * for a better first paint, but a default/cached/no-hint compile must still
 * respect the user's OS preference in the browser; that is the whole point of
 * the media query. Targets the plan's real selector (the stamped
 * `data-czap-boundary` attribute), and applies the end-state declarations so a
 * `from { opacity: 0 }` boundary settles VISIBLE instead of freezing hidden.
