A WKWebView runs no service worker, so the page's Keep button (#412) was not shown in the app and everything played from the server. Now the page asks the app to keep the file (keep, unkeep, clearKept), and the app answers with what it holds (kept, keepFailed) whether or not anything plays. The app fetches with a background URLSession, so a download goes on with the app closed, into Application Support (not backed up; the files can be fetched again), and Playback plays from the file when there is one. The DeadAir copy is kept under its own path, as the browser keeps it. Places and finishes reached offline wait in an outbox, newest per address, and go when the network is back. Checked in the simulator against a local server: kept /media/42 and /media/42/deadair, then with the server refusing /media, a fresh launch played each from the phone and asked the server for nothing. The page itself still needs a connection to open (#435). Deploy the app (build 6) before the page: a new page in an old app shows a Keep button nothing answers.
