/* ═══════════════════════════════════════════════════════════════════
   QUBBLE CALL — "The Sealed Channel"
   Calls are bubbles: they form (sonar rings), entangle (thread fuses,
   particles burst), and end by popping. Secrecy is the aesthetic —
   veiled glass, whispered mono copy, a classified-stamp SAS chip.
   Uses the established theme tokens from style.css.
