/* ==========================================
   SalmasFlix — Audio / WebRTC Call UI
   Extracted from components.css in Phase 7.2.

   Owns:
     - `.call-overlay` full-screen ringing UI (avatar, pulse ring,
       shake animation, Accept / Decline / Mute / End buttons)
     - `.call-bubble` floating minimized indicator during an active call
       (bottom-left of the screen, canvas-backed waveform)
     - `.call-bubble-popup` hover popover with Mute / End

   Accepts (green #2ecc71) and decline (red #e74c3c) stay literal because
   they're universally recognized semantic colors — a dialer that flips
   green-means-reject with every theme preset would be a usability bug.
   Literal colors here are the same documented exceptions as CLAUDE.md
   lists ("semantic green for success", "red for danger").
