/* ============ THE SIGNAL ATLAS — coverage principal act ============
   Pinned ~300vh scroll cinema on /coverage/. One addressed timeline,
   three beats: Leaving → Landing → Connected.
   Photographic backdrops only; scrims for legibility. Transform/opacity
   animation only. html.ca-armed covers the pre-init flash; .ca-on is the
   steady-state stage selector. Without JS+GSAP the beats read as a
   normal stacked section. */
