/* ───────────────────────────────────────────────────────────────────────────
   Skindra Landing — animated product demos ("Scan. Versteh. Pflege.")
   One phone loops through three product moments (scan → ingredient check →
   plan). Three switchable presentation TYPES share that phone:
     · keynote — centered phone, calm gradient stage, minimal caption
     · float   — tilted phone, UI elements float out with parallax depth
     · story   — split layout, chapters highlight in sync with the phone
   Phase is driven by JS toggling [data-phase] on .demos; CSS handles all the
   easing. Autoplay + seamless loop; full static fallback under reduced-motion.
