/* ============================================================================
   call.css — Phase R7 — Call pane (green identity).

   Green is the active-life color — the moment of connection. The call
   stages are full-screen takeovers presented via YStage, layered over
   the existing call idle card. They use the contact's avatar_full and
   background_full where available (R5b/R5c) so the visual carries the
   relationship.

   Three stage flavors share the .cs-stage shell:
     • .cs-incoming  — caller's avatar full-bleed, breathing ring
     • .cs-outgoing  — recipient's avatar, ringback ripple
     • .cs-incall    — active call surface; remote video center,
       self-video corner, action bar at bottom
