 // Standalone, login-free video page for a shared /watch/<token> link. Rendered OUTSIDE the app
 // tree (no auth, no providers) — like the /privacy and /terms pages. Uses plain fetch and a tiny
 // self-contained i18n dict (the public viewer has no app language preference).
 
+// Keep audio playing when the page is backgrounded (iOS Safari/Brave otherwise suspend a <video>
+// the moment you leave the tab — the "background playback" a native app / YouTube Premium gets). Two
+// pieces: (1) route the element's audio through a Web Audio graph — once that graph is live, iOS
+// keeps the audio session running in the background while the video frame freezes; (2) Media Session
+// metadata + handlers, which give lock-screen controls AND signal the OS that media is active. The
+// file is same-origin (served by us), so createMediaElementSource isn't CORS-tainted. All of it is
+// best-effort: any unsupported bit falls back to the plain <video>. Set up lazily on the first play
+// (a user gesture — required to create/resume an AudioContext) and only once (a second
+// createMediaElementSource on the same element throws).
