/**
 * Magna AI - Voice Call Styles
 *
 * Call screen overlay UI for real-time voice calls.
 *
 * ★ PORTED from ConfidenceTalk `public/css/voice-call.css` (2026-10-01).
 *   Prefix-adapted `ct-` → `aisg-`. Every class below was verified against the
 *   23 `aisg-voice-call-*` classes ACTUALLY rendered by `class-public.php`.
 *
 * ★ THEME-CONFORMANT. The card reads the theme token with a literal fallback —
 *   the CT original hardcoded the default gradient. The CT avatar used
 *   `var(--color-primary-gradient, ...)`; that var does NOT exist in AISG, so
 *   it is re-pointed at the AISG brand token.
 *
 * @package AISG
