Negative prompt policy
Use exclusions the way this surface expects.
No public official negative grammar is documented. Keep exclusions as clear positive scene constraints instead of inventing a negative block.

Reliability constraints
- Use 4–8 focused sentences rather than tags or keyword bags.
- Explicit dialogue should be quoted and paired with audio generation.
- Exact on-screen text remains unreliable; add critical titles in post-production.
