   MOTION SYSTEM
   One easing, three durations, four behaviours. Nothing else moves.
   1. Load:    page headline words rise in, then intro, buttons, illustration.
   2. Scroll:  section headings reveal word by word; blocks fade up, once.
   3. Hover:   buttons nudge their arrow and press on click; cards respond.
   4. Ambient: only the hero illustration breathes (the tangle drifts, the
               orange line flows). Paused when off-screen.
   Everything is switched off for prefers-reduced-motion.
