"""The intern is Devon, not Devin.

Whisper heard "Devin" in 21 of 58 transcripts because the initial prompt in
backend/services/transcription.py never seeded his name as a proper noun. That
was invisible while transcripts were plain .txt nobody read; now they render as
indexed text on every episode page, so a regression would be public.

The durable fix is seeding "Devon" in the Whisper initial prompt. This test
catches it if that regresses or a new transcript slips through.
