/* ─────────────────────────────────────────────────────────────────────────
   Motion Kit — Zero-JS motion tracks
   Ported from motion-kit-starter (master): builder/renderers/html/
   css-native-motion.ts + view-transitions.ts. Scroll-driven reveals run on the
   compositor thread; page transitions are native cross-document crossfades —
   0 KB JavaScript, no bundle, no CDN: the most DACH/PDPA-compliant motion track.
   Progressive-enhancement contract: every hidden/offset pre-animation state
   lives ONLY inside @supports (animation-timeline) + prefers-reduced-motion:
   no-preference, so unsupported browsers and reduced-motion visitors always see
   static, fully-visible content (enhancement, never "hide and hope"). Kept in
   this external stylesheet, never inline, so it satisfies the site CSP
   (style-src 'self'). Recipe keyframes/ranges are the kit's verbatim; the
   selectors are this site's own (no per-element data-attributes needed). */
