* Production

Get a signed URL to upload a file directly to storage, bypassing the server. This is the recommended upload method for large files.

**Flow:**

1. Call this endpoint with content\_type and file\_size\_bytes
2. POST to the returned upload\_url with header `x-goog-resumable: start` to get a session URI
3. PUT your file content to the session URI (supports chunked/resumable uploads)
4. Use the returned file\_id as input to generation endpoints

Allowed types: application/x-zip-compressed, application/zip, audio/mpeg, audio/wav, image/jpeg, image/png, image/webp, video/mp4\. Max size: 64 MB. Upload URL expires in 15 minutes.
