Integration notes

How partner applications consume the delivery origin.

Master playlist	`GET /v2/media/index.m3u8`
Variant playlists	`segments/720p.m3u8`, `segments/1080p.m3u8`
Segment naming	opaque, issued by the manifest
Caching	segments immutable, playlists short TTL
Auth	signed query parameters

Direct enumeration of the segment path is not supported and returns an error. Clients must follow the manifest.
