/*
 * Showcase layer. Loaded after assets/style.css and any page <style>, so it
 * refines every page without touching their markup.
 *
 * Rules it follows (Emil Kowalski's skills + Apple's motion/materials notes):
 *  - Animate only transform and opacity; name the properties, never "all".
 *  - ease-out for enter/exit, UI motion under 300ms, exits faster than enters.
 *  - Press feedback on pointer-down (scale 0.97), hover only where hover exists.
 *  - Reduced motion = fewer, gentler animations (opacity stays, movement goes).
 *  - Mobile-native: tap highlight off, 16px inputs, safe areas, dvh, no sticky hover.
 *  - Break-UI: nothing may overflow at 320px or 200% zoom; long words wrap.
