/* ══════════════════════════════════════════════
   PHONE STORY: scroll-pinned phone that travels
   office → building → pocket (homepage, after hero).
   Driven by phone-story.js, which writes onto .ps-stage:
     --in    0→1  phone rises into place as the section pins
     --t1    0→1  office → street (camera pushes through)
     --t2    0→1  day → evening (pocket scene fades in)
     --sink  0→1  phone drops into the pocket
     --l0/--l1    linear progress through the office / street
                  scenes, so something always moves as you scroll
     --mx/--my    pointer, -1..1
   plus data-scene (0/1/2) for the discrete state changes.
