   script or logs. Anyone holding the link is signed in there with full access, so keep it out of the repo and `.env` backups. Or set `AUDIOBOOKS_SSO_SECRET`
   (and optionally `AUDIOBOOKS_SSO_URL`, default `<AUDIOBOOKS_URL>/sso`) for short-lived signed links: `?token=<body>.<sig>`, where `body` is base64url JSON
   `{u, id, exp, n}` and `sig` is the base64url HMAC-SHA256 of `body`. Without either, the plain site opens and the saved username can be copied.
+- **Books**: an e-book reader for **EPUB, PDF, DOCX, MOBI, AZW and AZW3** (Media group; give it to people in Settings -> People as *Books*). Add files with the button or by dropping them on the page (up to 300 MB each; the server checks a file really is what its name says and does not store the same book twice). Titles, authors and covers are read out of the books in the browser; long-press or right-click a book to edit, download or delete it. Each person has their own shelf in `/data/users/<id>/books/`.
+  - **Reading**: EPUB uses epub.js (pages or scroll, two-page spreads on wide screens), PDF uses pdf.js (continuous scroll, zoom, selectable text, dark and sepia tints) DOCX is converted to HTML by mammoth, and MOBI, AZW and AZW3 are read by `@lingo-reader/mobi-parser`; both are shown in a frame that cannot run scripts (scroll only, with contents from the book or its headings). Contents, search inside the book, a progress slider, tap the edges or use the arrow keys, swipe on touch screens, tap the middle to hide the bars. Appearance (theme, text size, font, line spacing, margins, layout, zoom) is remembered on each device.
+  - **Synced**: where you got to, bookmarks, highlights (four colours) and notes are kept on the server, so a book opens where you left off on any device; two devices adding notes at once keep both (the newest edit of the same note wins). Continue reading on the library page, sorting and search, and *Copy as text* exports a book's notes.
+  - **Book store** (Books -> Book store): search free, DRM-free books from **Project Gutenberg** (its own catalogue feed), **Standard Ebooks** (its public website: its OPDS feed is for paying members only, so the hub reads the public search pages and downloads the free EPUB), the **Internet Archive** (public-domain EPUBs only; borrow-only items are refused) and any **OPDS catalogue** an admin adds under *Catalogues* (Calibre-Web, Kavita, Komga and so on; an optional username and password are kept encrypted on the server and never sent to the browser). One search covers every source, results show their cover and source, and *Add to library* downloads the book on the server straight onto your shelf. The server only ever contacts a source's own addresses (redirects to other sites are refused), covers come through the hub, and a catalogue book must live on that catalogue's own address. Settings: `GUTENBERG_URL`, `STANDARD_EBOOKS_URL` and `ARCHIVE_URL` can point at mirrors. `node tools/store-test.js` tests it against fake catalogues; it was also tried against the live Project Gutenberg, Standard Ebooks and Internet Archive (searches, and real EPUBs downloaded); if one of them changes its pages or feed, the line under the search box names the source that failed.
+  - The reader scripts are in `public/vendor/reader/` (epub.js, JSZip, pdf.js, mammoth, the MOBI parser) and load only when a book is opened or added. `node tools/books-test.js` tests the server; `python3 tools/mkbooks.py <dir>` makes a small EPUB, PDF and MOBI to try. **DRM-protected books are refused** (a Kindle file with copy protection is detected on upload and the reason is shown); only DRM-free books work. The MOBI reader was tried on a generated MOBI 6 file, not on real Kindle files, so tell me about any book that opens oddly. Not included: text-to-speech, offline reading.
+  **Free audiobooks** (Audiobooks -> Free audiobooks; works without any audiobook sign-in): search **LibriVox**, thousands of public-domain books read aloud by volunteers, by title or author. A book shows its length, language, description and chapters; *Play* (or *Resume*) queues every chapter in the same player as Music so the next one follows by itself, and starting a book puts it on your shelf (*My free audiobooks*, with a progress bar; *Remove from shelf* in the book's sheet). Where you got to is kept on the server per person, so it follows you between devices. The hub searches LibriVox and hands the browser each chapter's address, but only addresses on LibriVox or the Internet Archive, which hosts the recordings; covers come through the hub. `LIBRIVOX_URL` points at a mirror. `node tools/librivox-test.js` tests it against a fake LibriVox; it has not been run against the live site from the build environment.
+- **Radio**: internet radio, with **The Journey FM** (Liberty University, Lynchburg, Virginia; MP3 192 kbps, `http://ic.liberty.edu:8000/WRVL`) always on top, showing what is playing now and the last songs played from the station's own feed. Below it, search thousands of stations from the community [Radio Browser](https://www.radio-browser.info/) directory (free, no key) by name or with quick topic chips (Christian, Worship, Gospel, Talk, News, Classical, Jazz...). The heart saves a station to *My stations* (your own list). Stations play in the same player as Music, so they keep playing as you move between tabs. The hub fetches each stream itself and passes it on, because many stations only offer plain http, which a browser refuses to play inside an https page; it also reads the song title carried in the stream (the player shows it) and fetches station logos. The hub never connects to private, local or link-local addresses for a station. Give it to people in Settings -> People (Radio). `JOURNEYFM_STREAM_URL`, `JOURNEYFM_NOW_URL` and `RADIO_BROWSER_URL` can override the addresses. `node tools/radio-test.js` tests it against fake stations; the real Journey stream could not be reached from the build environment, so if it will not play, open the station's own *Website* button and tell me what changed. Not included: HLS-only stations, recording, alarms.
+- **Verse By Verse** (Podcast -> *Verse By Verse*; needs only the Podcast tab, not Podgrab): free verse-by-verse Bible teaching from [Verse By Verse Ministry International](https://versebyverseministry.org). Browse the ministry's studies (about 80: Old and New Testament books, topical series, single teachings, women's and youth), search them, and open a study to see its lessons with dates and summaries. *Start* / *Continue* plays the study lesson after lesson in the same player as Music, a lesson resumes where you left off (kept on the server per person, so it follows you between devices), and each lesson's handout (PDF) opens from *Notes*. The hub reads the study list from the ministry's category pages and the lessons from each study's own podcast feed (`/bible-studies/<study>/podcast.xml`), keeps what it read for 30 to 60 minutes so the ministry's site is not asked on every visit, and sends the browser straight to the ministry's media server for the audio. Only the ministry's own addresses are ever used. `VBV_URL` can point at a mirror. `node tools/vbv-test.js` tests it against a fake copy of the site; it was also tried against the live site (80 studies, a study's lessons, audio and handout links). If the ministry redesigns its pages, the study list is the first thing that would break, and the screen would say so.
+- **Save to Files**: copy things into your own Seafile from where you find them. **Books** (long-press or right-click a book -> *Save to Files*), **free audiobooks** (a book's sheet -> *Save to Files*, one numbered MP3 per chapter in a folder) and **Verse By Verse** (a study's *Save to Files* button saves every lesson and handout, or just the audio or just the handouts; the download button on a lesson saves that one). You pick the library and folder (it remembers the last one); the hub makes a tidy subfolder (`Books`, `Audiobooks/<title>`, `Verse By Verse/<study>`), names files safely and in order, **skips anything already there** (so running it again fills in what is missing) and counts lessons that have no handout instead of failing. The hub does the downloading and uploading itself with the Seafile sign-in already saved for you, so a whole study (several GB) does not pass through your phone and keeps going if you tap *Hide*; a sheet shows progress, *Stop* cancels, and *Open folder* jumps to the result. It needs the Files tab and the tab the content comes from (Books, Audiobooks or Podcast); each person can have two saves running at once; files up to 500 MB. `node tools/savefiles-test.js` tests it against a fake Seafile.
+- **Bible**: the **Berean Standard Bible** (BSB, public domain: https://berean.bible/), all 66 books, with its section headings, poetry layout and footnotes. The whole text is one file (`public/vendor/bible/bsb.json`, about 1.5 MB compressed, made by `python3 tools/make-bsb.py` from the free Hello AO Bible API) that the browser loads once and keeps, so reading is instant and works offline. **Choose** a book and chapter, **search** for words (every word must be in the verse) or type a place (`John 3:16`, `1 cor 13:4-7`, `ps 23`), swipe or use the arrow keys to turn chapters, and tap verses to **highlight** (four colours), add a **note**, or **copy** them with their reference. Tap a small letter for a footnote. *My highlights and notes* lists everything. Your place, highlights and notes are kept on the server per person, so they follow you between devices; text size and font are remembered per device. Give it to people in Settings -> People (Bible). `node tools/bible-test.js` tests the saving and checks all 31,086 verses are in the file.
+- **Menu on a phone**: related tabs share one entry (**Listen**: Music, Radio, Podcast, Audiobooks; **Read**: Bible, Books; each part still needs its own permission), with a row of buttons under the top bar to switch between the parts (it remembers the last one you used). The **bottom bar** is yours to choose: *More* -> *Edit bottom bar* (up to five apps, in the order you tap them; it is saved to your account). **More** opens the **Apps** sheet: every app as a big icon, grouped, with the ones you used lately on top, a search box (typing *rad* finds Radio even though it lives under Listen) and unread badges. Home still shows one tile for each part. On a tablet or computer the side menu uses the same merged entries, and Ctrl/Cmd-K finds every page by name.
 - **Signal**: your Signal chats inside the app, **on desktop-class screens only** (a window at least 900 px wide with a mouse or trackpad; phones and touch tablets don't
   see it). Besides the Signal tab there is a chat button on **every** screen that opens a panel over whatever you are doing (close it with the x; the
   expand button opens the full page). New messages get your attention with a toast, a chime, the unread count in the browser tab title and on the installed app's icon, and
