/* ─────────────────────────────────────────────────────────────────────────
   Assistant Manager call — the phone-call screen.

   Deliberately shaped like a native call screen, because that is the whole
   idea: this is not a chat with audio bolted on, it is a call. The furniture
   people already know — a running timer, the caller's name large at the top,
   a grid of round controls, one red button to hang up — carries the metaphor
   without a word of explanation.

   The palette is ours, not Apple's: the pitch-green and cyan the rest of the
   site runs on, over the app's near-black, rather than the iOS blue-grey.
