/* Web voice call page — real-call feel, mobile-first, theme-driven.
 *
 * Visual hierarchy (top → bottom):
 *   1. Hub chip   — small pill with clinic name + e2e-encrypted shield
 *   2. Avatar     — big circular portrait with theme glow + state-driven ring
 *   3. Identity   — name + role ("AI receptionist")
 *   4. Waveform   — 32 thin bars driven by Web Audio AnalyserNode frequencies
 *   5. Status     — "Tap to call" / "Connecting…" / "Connected" / etc.
 *   6. Timer      — small monospace; only renders during a call
 *   7. Controls   — single CTA in idle; 3 icon-stacks (mute / speaker / end) in-call
 *   8. Disclaimer — small caps, neutral
