/* Hero content is STATIC (no entrance animation).
   Reason: on iOS Safari a keyframe animation that passes through opacity:0 can fail to paint and
   stay stuck at that start frame until a repaint (lock/unlock) is forced — leaving the hero text
   invisible on load. With no opacity animation there is nothing to get stuck: the hero is always
   painted at opacity:1. (Also better for LCP.) The video background still provides motion. */
