Die Player-Leiste sitzt in der Radio-Leiste an der Stelle von „läuft gerade“: am Desktop eine Zeile (Player, Lautstärke, Fokusmodus, Timer), am Handy zwei; die Fortschritts- bzw. Live-Linie läuft über die ganze Leiste. Der Fokusmodus zeigt den Sender weiter groß. sw v56. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

/**
|
||
* Podcasts in the browser: the phone app's podcast page on top of a browser
|
||
* version of what the app does in Kotlin.
|
||
*
|
||
* The page itself is diora-android's web-native/static/native-podcast.js,
|
||
* copied unchanged to /static/podcasts/ by tools/sync_podcast_ui.py. It talks
|
||
* to its host only through a small API (window.DioraNative in the app,
|
||
* window.DioraPodcastHost here) and hears back through window.__dioraPodcasts,
|
||
* __dioraPodcastsRefreshed and __dioraPlayer. This file is that host:
|
||
*
|
||
* - the state (feeds, queue, inbox, settings) from GET /podcasts/state/,
|
||
* kept in localStorage for a fast, offline-capable start (Podcasts.kt);
|
||
* - every change applied to that copy at once and sent to the server in
|
||
* order through an outbox that survives reloads and going offline;
|
||
* - a player of its own (not app.js's radio element) whose playlist is the
|
||
* queue, with the app's bookkeeping (RadioService.EpisodeTracker): resume,
|
||
* intro/outro, progress every 10 s and on pause, "played" near the end,
|
||
* moving on by itself, rewinding a little after a pause, per-podcast
|
||
* speed and volume, and the sleep timer (SleepTimer.kt);
|
||
* - lock-screen and media-key controls through navigator.mediaSession;
|
||
* - this device's playback settings in localStorage (PlaybackPrefs.kt).
|
||
*
|
||
* Radio and podcasts never play at the same time: starting an episode stops
|
||
* the radio (app.js stopPlayback), starting a station puts the episode away.
|
||
*
|
||
* In the app (and the desktop app) window.DioraNative exists and this file
|
||
* does nothing. Written without ?. and ?? so old WebViews can still parse it.
