/**
 * Agent UI — Right-edge slide-in chat panel.
 *
 * Stream 4 — replaces the pre-Stream-4 centred floating pill with a Linear /
 * Intercom-style panel that slides in from the right edge. Two states:
 *   data-state="closed"  → fully off-screen, no chrome
 *   data-state="open"    → on-screen, 360px wide (desktop), full-screen <640px
 *
 * Uses tokens from global.css / broker-portal.css. Zero hard-coded brand colours.
