/*
 * Diabec Human Call — floating "Talk to a specialist" button (human agent over
 * LiveKit), incoming-call banner, and in-call panel.
 * Sibling of diabec-voice-agent.* (the AI agent). Distinct `dhc-` prefix so the
 * two widgets never collide. FAB sits bottom-LEFT so it doesn't overlap the AI
 * FAB (bottom-right).
 * Palette matches diabec-base.css: --deep-green #2c3e1f, --amber-gold #c8a96e.
