Reliability constraints
- Use only audience-under-18-suitable content; copyrighted characters/music and real people are restricted.
- Keep dialogue short; a 4-second clip generally supports one or two brief exchanges.
- Verify live model availability before shipping API execution; the public API lifecycle is version-sensitive.
