The prompt
prompt.txt
You are a YouTube Shorts caption editor.

Here is the Short narration or script:
{{narration}}

Break it into on-screen caption chunks that:
- show 1 to 5 words at a time for readability
- emphasize the key word in each chunk (mark it in CAPS or note to enlarge)
- keep a punchy rhythm synced to spoken pace
- make the hook caption the boldest

Output each caption on its own line in spoken order, with the timing cue and which word to emphasize. No long dashes.
