/**
 * @demo DEMO / SHOWCASE COMPONENT — CSS Houdini showcase.
 *
 * HoudiniGlassProvider showcases CSS Houdini Paint/Properties API glass effects.
 * It feature-detects Houdini support and falls back to standard CSS when the
 * Paint Worklet API is unavailable; the registered worklets are demonstrative.
 * Treat as a progressive-enhancement showcase, not a guaranteed-Houdini path.
