/* ── TTS Word Highlight — Theme-aware Comet Trail ──

 * (Sunset / Teal / Cyber / etc) instead of the previous hardcoded rose.
 *
 * Fallback: if a browser doesn't support color-mix() the background rules
 * are dropped silently — the pop/scale animation still plays, so the
 * highlight is still visible, just without the colored wash.
