Description: Sora 2 native OpenAI format endpoint.

Agent guidance:
- Use this page when the user is asking about this specific route or model capability.
- Preserve endpoint paths, JSON keys, model IDs, and placeholder values exactly.
- Treat examples such as `sk-***`, `{BASE_URL}`, and `task_xxx` as safe placeholders, not real secrets.
