-`npx hyperframes tts` auto-detects a provider from env vars; explicit override via `--provider`.
+`npx hyperframes tts` synthesizes locally with Kokoro. It does not accept a
+`--provider` or `--words` flag. For HeyGen audio plus word timestamps, use the
+bundled `heygen-tts.mjs` script below.
 
 > **Run the Preflight first — no credential is not a green light to silently use the local voice.** Before generating a voiceover, complete the sign-in **Preflight** (see `../SKILL.md` → Preflight): run `npx hyperframes auth status`, recommend signing in, and **STOP for the user's choice** (sign in for HeyGen voices, or continue offline with local Kokoro). This applies to a one-off "generate a voiceover" request just as much as inside a full workflow.
