02 / Native media
SwiftUI around AVFoundation.
SwiftUI provides the product surface while AVFoundation anchors the media pipeline, keeping platform-specific media behavior close to the work that needs it.

03 / Background work
URLSession for the handoff.
Background URLSession gives work a chance to continue when the app is not in the foreground, and lets the product reconcile that work when the user returns.

04 / Cloud durability
D1 for truth, R2 for media.
Cloudflare D1 and R2 separate structured state from large media objects, giving the engineering model a clear place for metadata, durable status, and object storage.
