Negative prompt policy
Use exclusions the way this surface expects.

Reliability constraints
- For image-to-video, prioritize motion and camera change over restating image details.
- Wan 2.1/2.2 legacy flows are silent by default; do not imply native audio support.
- Multi-shot behavior is version-specific and should be gated to documented variants.
