/* ============================================================
   ORANO · "How it works" as a pinned scroll story
   Replaces the five stacked stages with one sticky phone whose
   screen plays each step as you scroll. Same mechanics as the
   "understanding" scrub above it (sticky pin + one scroll pass).

   hiw.js sets, on [data-hiw]:
     --i     active step (0-4)
     --p     progress through the whole story (0-1)
     --sway  phone tilt in degrees
     --fit   phone scale for the available height
   and on every screen and segment:
     --t     progress through that step (0 before, 1 after)

   Without hiw.js (or with reduced motion) the steps become tabs
   and every screen shows its finished state.
