## Notes

- Slybroadcast API delivery times are interpreted in Eastern Time and use 24-hour format (`YYYY-MM-DD HH:MM:SS`).
- Use one audio source per campaign request: account recording title, system audio file, public URL, local file, or AI text.
- Local and AI-generated files are staged first and must be publicly reachable for Slybroadcast to fetch.
