Create missing groups before adding the kiosk user (no netdev on 26.04)

Reported on a 26.04 offline install, first-boot step 2: useradd: group 'netdev' does not exist useradd refuses to create the user at all when any -G group is missing, which stopped provisioning. Ubuntu 26.04 Server's base system has audio, video, input and plugdev but no netdev (checked against the 26.04.1 ISO's /etc/group). provision_create_kiosk_user now `groupadd -f -r`s each supplementary group first (a no-op when it exists), then passes the same list to useradd.

 ## No user data in the repo
 Never write anything specific to a person's kiosk, network or accounts into
 this repository - not in code, tests, fixtures, docs, comments, commit
 messages, branch names or pull request text.
 That includes:
 - WiFi network names (SSIDs), passwords, keys and tokens
 - MAC addresses, IP addresses, hostnames and interface names taken from a
  real machine
 - usernames, email addresses, PINs and passwords
 - the URLs of someone's own sites or services
 - log output, screenshots or terminal output pasted in by a user
 When an example, test or fixture needs a value like these, use an obvious
 placeholder (`ExampleNet`, `192.0.2.10`, `aa:bb:cc:dd:ee:ff`, `wlan0`,
 `example.com`) instead of a real one. When debugging from output a user
 shares, keep it in the conversation or the scratchpad, not in a file in this
 repo, and leave it out of commit messages.

 **Booting it from Easy2Boot (or another multiboot USB)?** Some of their boot
 modes need the ISO stored in one unbroken piece on the drive, and a 3.5 GB
 file copied onto a well-used drive usually isn't. The symptom is a brief
 black screen and straight back to the menu. From Linux, with the drive
 plugged in:
 ```bash
 sudo iso/e2b-contig.sh --check /media/$USER/E2B/_ISO/LINUX/ubuntu-26.04.1-kiosk-offline-amd64.iso
 sudo iso/e2b-contig.sh /media/$USER/E2B/_ISO/LINUX/ubuntu-26.04.1-kiosk-offline-amd64.iso
 ```
 It rewrites just that file in one piece using ordinary file operations
 (never the filesystem's own structures), and keeps the original if anything
 doesn't verify. It temporarily fills the drive's free space to do it, so
 it takes a few minutes. `--move-out` lets it park the original on this
 computer when there isn't room for a second copy. NTFS, FAT32 and exFAT;
 on NTFS mounted through `ntfs-3g` it can usually read the layout, and if
 not it tells you to remount with the kernel's `ntfs3` driver. Also check
 the copy isn't simply damaged: `sha256sum` it on the build machine and on
 the drive.

 ### WiFi from the kiosk screen (consoles turned off)
 With virtual consoles switched off, there's no way to reach the admin menu at the kiosk itself. To join a WiFi network anyway, plug in a keyboard and press **Ctrl+Alt+Super+W** (Super = the Windows key). A WiFi screen opens:
 1. Enter the kiosk's code:
   - **Password protection on** (Core Settings → Password Protection & Lockout): the unlock **PIN**, or the unlock **password** if it's a password. Same slowdown after wrong tries as the lock screen.
   - **Password protection off:** the hidden-sites PIN (the F10 one - default `1234`).
   - Neither (protection off and the hidden-sites PIN turned off): no code is asked.
 2. Pick a network from the scan (strongest first, 🔒 = needs a password), or type its name.
 3. Type the password (empty for an open network) and press **Connect**.
 It writes the same netplan file as Core Settings → WiFi (`/etc/netplan/60-kiosk-wifi.yaml`), so the connection persists across reboots. If the kiosk gets no address within 30 seconds (usually a wrong password) the previous WiFi setting is put back. Esc or Close shuts the screen; it also closes itself after 5 minutes untouched. After 5 wrong codes in a row, entry pauses (30s, doubling up to 5 min).
 **About Fn:** the Fn key is handled inside most keyboards and never reaches the computer, so it isn't part of the combo - holding it too does no harm where Fn+W is still W. On compact keyboards where Fn+W is something else (often Up arrow), leave Fn out.
 **More than one WiFi adapter** (e.g. a built-in card and a USB dongle): a *WiFi adapter* dropdown appears at the top, and the status box lists every adapter with what it's connected to. Status, scan and connect act on the one you pick; by default it's the adapter that's connected right now.
 The root part is `/usr/local/bin/kiosk-wifi-helper` (status/scan/connect and region only). The app reaches it through a root-owned socket, `/run/kiosk-wifi-helper.sock` (`kiosk-wifi-helper.socket`, group-restricted to the kiosk user, `0660`), rather than `sudo`: the app can end up running with Linux's "no new privileges" flag, and then sudo refuses with *"The no new privileges flag is set"*. A passwordless-sudo rule (`/etc/sudoers.d/kiosk-wifi`) stays as a fallback. Existing kiosks get both with Advanced → Upgrade.

 - **Fix: the first-boot kiosk setup never started on 26.04.** Its service was ordered after cloud-init's final stage, which itself runs after `multi-user.target` - an ordering cycle that systemd broke by dropping the kiosk setup. It also "conflicted" with the tty1 login prompt, which systemd can resolve the same way. Both removed; checked with `systemd-analyze verify` against 26.04's own units. Rebuild the ISO to pick this up.

 - **Lock screen PINs and a separate boot code:** the unlock code and the boot code can each be a password or a 4-8 digit PIN (on-screen number pad, works on touch screens), and the boot lock can have its own code. Repeated wrong codes now pause the lock screen (30s, doubling to 5 min). Set in Core Settings → Password Protection & Lockout or the Web UI's Lockout page. Existing settings keep working unchanged (password, same code at boot).

 - **Privilege model:** the web service itself still runs as `$KIOSK_USER` with zero ambient `sudo`. A new narrow, allow-listed root helper is the only way it ever gains privilege — reachable only via a single-path passwordless sudo rule (generated and validated with `visudo -c -f` before being installed), and it re-checks its own fixed action allow-list before dispatching anything. Chosen over running the whole service as root after asking directly: since this repo has no login of its own by design, a request that reaches the web UI with no reverse proxy in front is effectively unauthenticated, so the allow-list bounds what that can actually do to five vetted actions, never a root shell.

 - **New: Web UI** (Addons → Web UI) — a small Node/Express app (`webui/`) giving a browser-based editor for Sites & Page Timing, Display & Interaction, and Password Protection & Lockout, the three Core Settings menus that are pure `config.json` read/write with no privileged system mutation involved. Runs as a systemd service under `$KIOSK_USER` (the same user Electron runs as), so it never needs `sudo` — it reads/writes `config.json` with normal filesystem permissions.
 - `webui/lib/config.js` re-implements `lib/config.sh`'s exact field list, defaults, and merge-on-save contract in JS — `kiosk-app/main.js` already reads the same `config.json` directly in JS, so this isn't a new pattern — meaning it can never silently clobber fields it doesn't track (Authelia's credentials, the unused quiet-hours fields, etc), the same failure mode previously fixed in `lib/config.sh`'s own history.
- **Login follows the kiosk's password protection.** With password protection on (Core Settings → Password Protection & Lockout), the Web UI asks for the same PIN/password the lock screen uses (a session lasts 12 hours; 5 wrong tries in a row slow it down like the lock screen does; changing the code signs every browser out). With protection off there is no login, so beyond a trusted LAN turn protection on or put it behind a reverse proxy (e.g. Caddy) with Authelia forward-auth — Authelia integration is out of scope for this repo. Direct LAN access with protection off has no authentication at all — treat it like SSH access to the kiosk.
+- **No login of its own, by design.** Authelia runs elsewhere; the expectation is a reverse proxy (e.g. Caddy) with Authelia forward-auth in front of it, the same way other self-hosted apps get protected — Authelia integration is explicitly out of scope for this repo. Direct LAN access with no proxy in front has no authentication at all — treat it like SSH access to the kiosk.
 - Deliberately narrow scope for this first pass: WiFi, Timezone, Power/Display/Quiet Hours, Complete Uninstall, every other addon, and everything in Advanced remain terminal-only — a network-facing process shouldn't be handed `sudo`-level system mutation (netplan, `timedatectl`, `apt`, systemd timers) without a lot more thought than this pass gives it. A "restart kiosk display" action was left out for the same reason — would need a narrow polkit grant, a follow-up.
 - Wired into Complete Uninstall (`webui_do_uninstall`) and Clone Settings (addon-presence detection) the same way every other addon is.

 # iso/e2b-contig.sh - Make a file on a USB drive contiguous, from Linux.
 #
 # Easy2Boot (and other multiboot loaders) can only boot some ISO files when
 # they sit on the drive in one unbroken piece. A big ISO copied onto a
 # well-used drive usually lands in several pieces, and Linux has no
 # defragmenter for NTFS/FAT32/exFAT. This rewrites the one file so it is
 # contiguous, using only ordinary file operations - it never writes
 # filesystem structures directly, so the worst case is "still not
 # contiguous", not a damaged drive.
 #
 # How: a plain copy just fills the drive's scattered free gaps again. So
 #   1. fill the free space with temporary filler files (plugging every gap),
 #   2. find the longest physically unbroken run among them and free exactly
 #      that run,
 #   3. write the copy - the only free space left is that run,
 #   4. delete the fillers, verify the copy's SHA-256, swap it in.
 # This writes about as much data as the drive has free (progress shown) -
 # minutes on USB 3, longer on USB 2 or a nearly empty big drive.
 #
 # If there's no unbroken run as big as the file while the original is still
 # on the drive, --move-out first parks the original on this computer's disk
 # (checksummed), deletes it from the drive to free its pieces, and retries.
 #
 # Usage:
 #   sudo iso/e2b-contig.sh [--check] [--move-out] [--temp-dir DIR] [--yes] FILE...
 #
 #   --check       Only report whether each file is contiguous.
 #   --move-out    Allowed to park the original on this computer if needed
 #                 (default temp dir: /var/tmp).
 #   --temp-dir D  Where to park it.
 #   --yes         Don't ask for confirmation.
 #
 # Works with NTFS (ntfs-3g or the ntfs3 kernel driver), FAT32 and exFAT -
 # anything filefrag can map. Run as root (filefrag needs it on most of

 # Room for Books: a home library (Koha + the Room for Books site, in Docker)
 A self-hosted library catalogue you can set up in one command:
 ```bash
 sudo ./install.sh
 ```
 It installs Docker if it is missing, generates the passwords, builds the images,
 starts everything and prints the addresses and your login. Running it again is safe;
 it never overwrites your `.env` (passwords) or your data.
 | What | Address | Login |
 |---|---|---|
 | **Your library**: add books, find a book, people, lending, labels, settings | `http://<this machine>:8081` | `admin` and the generated password |
 | **Add books** (scan an ISBN, or use the phone camera) | `http://<this machine>:8081/add/` | same login (asked once more) |
 | **Public catalogue** (search only, for a kiosk or visitors) | `http://<this machine>:8080` | none |
 For home use you only need the first address: sign in to **Your library**, and use the **Add books**
 button on its home page. The Add books page has a **Find a book** tab (title, author or ISBN, with the
 shelf and whether it is on the shelf or checked out) and a **Manage** link back to the staff site. The
 public catalogue exists for a kiosk screen or visitors and does not need a login. (Koha gives its public and
 staff sites the same URL shapes, so they cannot share one address; Add books can, and does.)
 Ports move up to the next free number if one is taken; the final addresses are printed
 at the end and by `sudo ./install.sh --status`. Add books is also reachable directly on its own port
 (`8082`), which is handy behind a proxy but not needed otherwise.
 ## What it is made of
 * **Koha**: the open-source library system, built from the Koha project's own Debian
  packages (no third-party Koha images). Installed and configured automatically; there is
  no web installer to click through.
 * **Quick Add** (`quickadd/`): a small page that turns "scan an ISBN" into "book added".
 * **MariaDB**: the database.
 Needs about 2 GB of RAM and 3 GB of disk. The first build takes 5-10 minutes.
 ## Adding books
 Open **Add books** and scan (or type) an ISBN, then Enter. A USB or Bluetooth barcode
 scanner works as a keyboard, so just scan.
 1. The ISBN is looked up on the Library of Congress over **Z39.50**. If that server cannot
   be reached (many networks block port 210), **Open Library** over HTTPS is used instead.
 2. If you already have the title, you are asked whether to add **another copy**.
 3. Otherwise the record is added with a barcode (see **Barcodes** below), the Dewey (or LC) call
   number from the record, the item type chosen at the top (Book, Movie, Music, Game) and the shelf
   you picked.
 4. Nothing found? A short form lets you type the title and it is added anyway.
 5. **Undo** removes an item (and the record, if it was the only copy). Freed barcode numbers
   are never reused, because a label may already be printed.
 DVDs and CDs work by scanning the **UPC** under the barcode; they are matched against what you
 own the same way ISBNs are. Few UPCs are in the free catalogues, so expect to type a title
 for many of them.
 The page beeps: high for added, double for a duplicate, low for not found. You can scan a
 stack of books without looking at the screen.
 ### Scanning with a phone camera
 Open the Add books page in your phone's browser and tap **Scan with camera**. Your phone's own camera app
 opens; take a photo with the barcode filling the frame, and the book is looked up and added just as if you had
 typed it. In "scan a pre-printed sticker" mode the same button appears on the sticker step.
 * It works over plain HTTP on both iPhone and Android: the photo is taken by the phone's camera app, shrunk on
  the phone, and read on the server (`zbarimg`). Only JPEG and PNG photos are accepted.
 * It reads ISBN-13 and ISBN-10 barcodes, and UPC/EAN codes on discs and games.
 * Tips: get close so the barcode fills most of the frame, keep it flat and well lit, and hold steady. If it
  can't read the photo you are told, and nothing is added.
 * A live viewfinder that reads continuously would need HTTPS (browsers only allow that for secure pages); a
  Bluetooth scanner paired to the phone also works, since it types into the page.
 ## Barcodes: your choice
 Barcodes are optional. Open **Barcodes and settings** at the bottom of the Add books page:
 | Choice | What happens |
 |---|---|
 | **Number them automatically** (default) | Each new item gets the next number, zero-padded to 7 digits (`0000042`). |
 | **I stick a pre-printed barcode on each one** | After the ISBN is recognised you scan the sticker on the book. A sticker that is already in use is refused. |
 | **No barcodes for now** | Items are added without one; the catalogue still shows them. |
 Later, in the same panel:
 * **Give them barcodes** numbers every item that has none, in one go, and shows the range to print.
 * **Print a sheet of barcodes ahead of time** reserves a block (say 80 numbers), and the link opens
  Koha's label printer with that range filled in. Print the sheet, and stick the labels on whenever you like.
  Reserved numbers are never handed out again.
 Good to know:
 * Koha's range printer needs both ends to be the same length, so barcodes are fixed-width digits. They are
  **at least 7 digits** on purpose: 6-digit all-number Code 39 barcodes can be misread as the pharmacy
  "Code 32" format by some scanners (checked with a decoder: 7 digits read back perfectly, 6 did not).
 * Prefixes (such as `HOME-0042`) are not offered: Koha's range printer cannot print them.
 * Barcode types Koha can print: Code 39 (default, read by every scanner), Code 39 with a Modulo-43 or
  Modulo-10 check digit (needs a scanner set up for check digits), EAN-13 (exactly 12-13 digits),
  COOP 2 of 5 and Industrial 2 of 5. Change it under *Cataloging → Label creator → Label layouts*.
 * Koha's own automatic barcode is switched off so there is one numbering scheme. Items added in the staff
  interface have no barcode until you press **Give them barcodes**.
 ## Printing labels
 From the Add books page, **Print labels** opens Koha's label printer with the barcode range of what you
 just added filled in (you may be asked to log in to the staff interface). Pick a template and layout
 and print at 100% scale (not "fit to page") so the labels line up.
 | Template | Sheet |
 |---|---|
 | Avery 5160, 1 x 2-5/8 | 30 per sheet; spine label + barcode |
 | Avery 5167, 1/2 x 1-3/4 | 80 per sheet; barcode only |
 | Demco spine, 1 x 1.5 | 50 per sheet; call number on up to four lines |
 | Layout | Prints |
 |---|---|
 | Spine + barcode | call number (split over lines) with the barcode below |
 | Spine - call number | call number only |
 | Barcode only | barcode |
 ## People and lending
 Lending is set up for a home library: 3-week loans, up to 25 items, 3 renewals, **no fines**.
 Change it under *Administration → Circulation and fines rules*.
 1. **Add a person**: staff interface → *Patrons → New patron → Friend / borrower*. Only the name is
   required; the **library card number is assigned automatically** (`1000001`, `1000002`, ...). Numbers
   start well away from item barcodes so a scan can never mean both.
 2. **Print the card**: *Tools → Patron card creator → New batch*, add the patron's number, *Export card
   batch*, template **Avery 5371**, layout **Library card**. The card carries the name and a scannable barcode.
 3. **Check out**: *Circulation → Check out*. Scan the person's card, then scan each book. The due date appears
   on screen.
 4. **Check in**: *Circulation → Check in*, scan the book.
 A USB or Bluetooth scanner types the number and presses Enter, so it works in all of these boxes.
 ## Finding the books
 The public catalogue searches title, author, subject and ISBN, and shows each copy's
 availability, call number and **shelving location**.
 On the Add books page, pick the **Shelf / room** before you scan; every book you add
 gets it. The choice is saved on the server, so every device shares it. If all your books are in one
 place, leave it on *(not set / all in one place)*; nothing is shown and nothing needs changing. Change it
 whenever you move to another shelf.
 The list comes from the staff interface (*Administration → Authorized values → LOC*), which
 starts with a few rooms such as Fiction, General stacks and Reference. Add your own there,
 for example "Living room - bookcase 2". (Koha has no way to add a room from the Add books page.)
 ## Common tasks
 ```bash
 sudo ./install.sh --status     # addresses, login, container health
 sudo ./install.sh --update     # rebuild with the latest Koha release (your data is kept)
 sudo ./install.sh --stop       # stop everything
 sudo ./install.sh --start      # start again
 sudo docker logs -f library-koha
 ```
 Settings live in `.env` (created on first run, mode 600). Useful ones:
 | Setting | Meaning |
 |---|---|
 | `BIND_ADDR` | `0.0.0.0` (default) reachable from the network, `127.0.0.1` this machine only. Docker bypasses `ufw`, so this is the setting that actually limits access |
 | `OPAC_PORT`, `STAFF_PORT`, `QUICKADD_PORT` | published ports |
 | `QUICKADD_SOURCES` | lookup order, e.g. `z3950:lx2.loc.gov:210/LCDB,openlibrary`. Add more `z3950:host:port/database` entries |
 | `LIBRARY_NAME` | name shown on the catalogue (first install only) |
 After editing `.env` run `sudo docker compose up -d`.
 ## Behind a proxy or on a locked-down network
 * Building behind a TLS-inspecting proxy: `sudo EXTRA_CA=/path/to/ca.crt ./install.sh`.
 * Docker Hub limits anonymous pulls (HTTP 429). The installer retries with a growing pause.
 * Z39.50 needs outbound TCP port 210. Without it, Open Library is used automatically.
 ## Backups
 Your books live in two Docker volumes: `library_db-data` (the catalogue) and
 `library_koha-data` (search index, uploads). Back up the database with:
 ```bash
 sudo docker exec library-db sh -c 'exec mariadb-dump -uroot -p"$MARIADB_ROOT_PASSWORD" --single-transaction koha_library' > library-backup.sql
 ```
 The search index is rebuilt automatically if it is lost.
 ## Security notes
 * The staff interface and Quick Add are protected by the generated password, over plain HTTP.
  Keep them on a trusted network, or set `BIND_ADDR=127.0.0.1` and put a reverse proxy with
  HTTPS in front.
 * Quick Add uses the staff `admin` login to talk to Koha's API.

                      servers, label templates/layouts)
 quickadd/             the scan-to-add service (Python standard library + yaz)
 ```
 ## Signing in once
 Staff who are signed in to the library site (and allowed to edit the catalogue) open **Add books** without a second login. Koha itself confirms the sign-in; the shared secret is `SSO_SECRET` in `.env`. The read-only `guest` login still uses the Add books prompt, and the direct Add books port never accepts a Koha sign-in. If `SSO_SECRET` is empty, Add books just asks for its own login as before.
 ## The home page (the Room for Books site at `/add/`)
 One simple page: a **Look up** box (books by title, author or ISBN, and people by name or card number), four big buttons
 (**Check out**, **Return**, **Add books**, **Add a person**) and **Recently added** books with their covers. The **menu**
 (top right) holds the rest: browse all books, lend / return, people and library cards, barcodes and settings, export / import,
 and a link to Koha's own staff screens. Borrowers and the read-only guest see just the lookup, recent books and (borrowers) My books.
 **Adding by title:** on Add books, scan or type an ISBN to add it straight away; type a title or author instead and you get a list
 of matches (cover, author, year, publisher) from Open Library and the Library of Congress to choose from. Books you already have
 are marked, with an *Add another copy* button.
 ## Everyday use (details)
 One page for the day-to-day, so you rarely need Koha's own screens:
 - **Library**: a cover grid of everything you own. Search by title, author or ISBN; filter by shelf, format
  (book/DVD/CD) and status (on the shelf / checked out); sort by title, author or newest. Click a book for its
  page: copies with barcode, status, who has it and when it is due; change a copy's shelf or call number,
  add another copy, remove a copy, or delete the book. (Title/author edits are one click away in Koha.)
 - **Lend / return**: scan or type a library card number (or search by name), then scan books to check them out;
  "Return a book" takes a scan with no person needed; **Renew** extends a loan; the list below shows everything
  that is out, overdue ones flagged. Check-in goes through Koha's own check-in code, so holds and rules still apply.
 - **People**: add someone with just a name (the card number is assigned automatically), search, and
  **Print card** for a library card with a scannable Code 39 barcode.
 - **Add books**: scan an ISBN (or use the phone camera), as before.
 The read-only `guest` login only sees the Library and book pages (no copy status names, no editing, no lending).
 ### Collections, QR cards, more about a book
 - **Collections** (Kids, Cookbooks, ...) are per copy, shown on the book page next to the shelf, and filterable on the
  Library page. Choose **+ New collection...** (or **+ New shelf...**) in the dropdown to add one: no Koha screens needed.
 - **Library cards** carry a Code 39 barcode and a **QR code** of the card number. **Save as picture** makes an image to text
  or AirDrop to a phone; on Lend / return, **Scan card or phone QR with camera** reads either one from a photo.
  **Print everyone's cards** (People) lays out a sheet of cards.
 - **More about a book**: a description and subjects from Open Library, plus look-up links (Goodreads, LibraryThing,
  WorldCat). **AR BookFind** is a link only: Renaissance's terms forbid automated access, so nothing is fetched from it.
 ### Reading levels (AR) and spreadsheets
 AR BookFind has no public feed or import, and its terms forbid automated look-ups, so this site does not fetch from it.
 Instead: the book page has an **Open AR BookFind** link (plus **Copy title** to paste into its search) and boxes to record the
 **level, points and quiz number** you find there (the read-only guest sees them). **Library page -> Export / import** downloads
 `library.csv` (one row per copy, with any reading level) and imports a CSV of `isbn, level, points[, quiz]` you made yourself
 (for example from a spreadsheet or a Renaissance report you are entitled to export). Levels are stored in `reading-levels.json`
 in the Add books data volume, keyed by ISBN, so they survive a Koha reinstall and are included in the usual backups of that folder.
 ### Live camera scanning (needs HTTPS)
 Browsers only allow a live camera on HTTPS pages (or on the machine itself). Put the library site behind Caddy with a real
 certificate and **Live scan** buttons appear: Add books (scan a stack of ISBNs one after another), Lend / return (live card or
 phone-QR scan, live book check-out for the chosen person, live returns). Chrome on Android reads codes in the browser; other
 browsers send small camera frames to the server's decoder a couple of times a second. On plain HTTP the photo buttons stay.
 ### Copying reading levels from AR BookFind
 On the AR BookFind book page, select everything (Ctrl/Cmd+A), copy, and paste into the box on the book page here: the level,
 points, quiz number and interest level fill in by themselves; check them and press Save.
 ### Tags, and borrowers signing in
 - **Tags**: any number per book (to read, kids, signed...). Add and remove them on the book page; click one to see every
  book that has it; the Library page can filter by tag. They are stored in `tags.json` in the Add books data volume, which
  the usual backups of that folder include.
 - **Borrowers sign in**: every person gets a login, **their library card number + a password**. Adding someone shows
  their password once (a different easy one like `maple482`, or the same one for everyone: People -> *Sign-in passwords for new
  people*). *Give everyone a sign-in* covers people added earlier; *New password* resets one person. A borrower who signs in
  sees the library and a **My books** page: what they have out, when each is due (or overdue), **Renew**, and **Change my
  password**. They cannot lend, edit or see other people. Passwords are Koha's own patron passwords; this stack relaxes Koha's
  default strength rule (4+ characters instead of 8 with upper/lower/digit) once, at install or update.
  Ten wrong guesses from one address locks sign-in attempts from it for five minutes.
 ### Reading levels: pop-up or in-page AR BookFind
 The book page's AR box has **Open beside this page** (a pop-up window next to the book) and **Show it here** (AR BookFind inside the
 page; some browsers block its cookies inside another page, then use the pop-up). Either copies the title first so you can paste
 it into AR's search; AR's own page cannot be pre-filled from here.

 # menus/addon_library.sh - "Library Catalog" addon: a self-hosted library
 # catalogue (Koha) running in Docker, with a "Find a book" page on the kiosk.
 #
 # What gets installed (all from this checkout's library/ directory, deployed to
 # $LIBRARY_DIR - see library/README.md for the stack itself):
 #   - Koha: cataloguing, Z39.50 lookup, label printing, people and lending.
 #   - Quick Add: the "scan an ISBN, the book is added" page, with a Find a book tab.
 #   - MariaDB.
 # Docker itself is installed on demand (lib/docker.sh).
 #
 # Everything needs a login. The kiosk shows the "Find a book" page signed in as a
 # READ-ONLY guest login (Find a book is search only; the guest has no Koha account at
 # all, because Koha's own search permission also allows editing label layouts); the page
 # list stores that guest login like any other Basic Auth site. The admin login never
 # goes into the kiosk's config. The public catalogue (OPAC) is off by default.
 #
 # Whether other devices on the LAN can reach the library site is the "Network access"
 # choice below. NOTE: Docker publishes ports straight through iptables and bypasses
 # ufw, so "this kiosk only" is enforced by binding the published ports to 127.0.0.1
 # (BIND_ADDR in library/.env), not by firewall rules.
 #
 # Depends on: lib/menu.sh, lib/config.sh, lib/docker.sh being sourced first.
