/* HaiGames SDK — Shared chat panel styles
 *
 * Namespace: .hg-cp-*
 * Depends on .hg-overlay (z-index 600) as the shell; panel sits at 650.
 * Self-contained (no CSS vars required from host); dark theme + purple accent
 * so it visually matches TTT / RPS / Emoji sheets and companion.html bubbles.
