You are expanding a one-line idea into a 4-shot storyboard. Produce:

1. **Beats.** Three-act structure in three sentences (hook / shift / payoff).
2. **Shot 1–4.** Each shot: scene description (≤ 30 words), action beat, audio note, on-screen text if any.
3. **Character lock.** One paragraph the provider prompts will reuse verbatim so the character stays consistent across all four shots.

Never invent provider-specific syntax in the scene descriptions — those happen at `/video:scene` time.
