/**
 * Svelte action to add a Material 3 ripple effect to an element.
 *
 * Uses the canonical `--smrt-color-primary` token (the SMRT theme system only
 * ever emits `--smrt-color-*`; the legacy `--md-sys-*` namespace is not produced
 * by the canonical providers), falling back to `currentColor`.
 *
 * Respects `prefers-reduced-motion`: when the user requests reduced motion the
 * ripple is skipped entirely. On `destroy()` all pending ripple spans, their
 * removal timeouts, and the window pointer-up listeners are cleaned up so an
 * unmount mid-press cannot leak DOM nodes or listeners.
