"""Whisper mishears recurring show names; correct them after transcription.

publish_episode.py transcribes with LightningWhisperMLX, whose transcribe()
signature is (audio_path, language) — it accepts no initial_prompt, so there is
no way to condition it on proper nouns the way make_clips.py does with
mlx_whisper. The intern came out as "Devin" in 21 of 58 published transcripts
because of this.

A deterministic pass over the finished text fixes the known names without
swapping the transcription engine.
