/**
 * diora Home: what you were in the middle of, one click away — the book you're
 * reading, the next episode, the news, your stations, Ambient.
 *
 * Built only from what the page already has: the book list (app.js), the
 * podcast host (window.DioraPodcastHost in the browser and diora desktop,
 * window.DioraNative in the Android app), the saved stations in the radio tab
 * Drift (app.js __dioraAmbient*) and the feed reader (feeds.js __dioraFeeds*). Renders into #tab-home; the same file runs
 * in the browser, diora desktop and the Android app (copied with static/js/).
 * Written without ?. and ?? so old WebViews can still parse it.
