   1-to-1 calls (public/js/calls.js)
   - .call: the call screen. It is its own layer on top of everything (sheets, the story
     viewer, toasts), so moving to another page never closes it. Full screen on phones, a
     card in the middle of the screen on wider screens.
   - .call-bar: the call made small, a bar at the top so the app stays usable while you talk.
   Colours come from base.css, so both themes work. Accept is green, Decline and Hang up red.
