Settings had grown to 21 rows in one list. It opens on five groups (This
device, Display, GNSS and radio, Network, System); Enter opens one, Back
returns to the groups, and Back from the groups leaves Settings.
SettingsMenu holds the groups and which one is open (host-tested: every
setting is in exactly one group). The guide, the how-tos, the README,
the scripts' messages and the firmware's own name the new paths, such as
"Settings > System > Firmware".

Settings > Theme and Settings > Light or dark pick the colours of every
screen (issue #10): roro9stack (the website's, the default), Catppuccin,
Dracula, Nord, ANSI terminal, Gruvbox and Solarized.
- A palette is 14 roles (lib/ui/src/palette.h). theme::kText and the
others are now references into the one in use, so the Apps are
unchanged; the main loop applies it when a Setting changes.
- Every colour is one the RGB332 frame buffer holds exactly: the themes'
own were rounded, and those that fell together or lost contrast were
picked by hand. test_palette checks exactness and 18 contrast ratios
for each palette.
- The Sky view's constellation colours come from the theme.
- `theme [0-6] [light|dark]` on the consoles.

The Launcher shows the Apps as a 4 x 3 grid of 32 x 32 icons, the
selected one's name under it (issue #9). The icons are the website's
own, doubled, and two drawn the same way for SSH and the Shell; they
are PNGs in assets/icons, turned into arrays by scripts/make_icons.py,
which CI checks. The selected tile is the website's: dark blue on cyan,
with notched corners.
- GridModel (lib/ui, host-tested) holds the selection and the scrolling.
- App::badge(): a dot on the tile for unread IRC messages, a Track
recording, a Capture running, an SSH session open.
- Settings > Launcher: Grid or List.

The theme takes the website's palette, each a colour the RGB332 frame
buffer holds exactly: cyan for the accent, a selected row and a chosen
button in cyan with dark blue text, a slate Status Bar (the grey it
asked for was shown as a dull olive), the website's orange for
warnings and its pink for messages. "Good" (a Fix, the quietest
channel) keeps a green of its own, which the website doesn't have.

The bottom-line message (a malformed address, not enough memory, a
session still closing) is timed from millis() when a key sets it, and
update() compared that with the pass's own time, read before the keys
were handled. The unsigned difference wrapped, so the message was
cleared before it was ever drawn: Enter on a new connection that was
refused looked like it did nothing.

The MeshCore preset is the default for a new device, in the Settings and
in the radio before the Scanner is opened. The setting now accepts it:
it only took the 7 Meshtastic presets, so MeshCore picked in the App was
not saved.
Messages on MeshCore's public channel are decrypted with the channel's
published key (AES-128, checked with 2 bytes of HMAC-SHA256): the row
shows who says they sent it and the start of the text, the details the
sender, the time and the whole text. Other channels and private messages
stay encrypted.

- MeshCore joins the presets (EU/UK Narrow: 869.618 MHz, 62.5 kHz, SF8,
CR 4/8, sync 0x12), after the Meshtastic ones so stored choices keep
their number; `lora preset MeshCore` on the console
- lib/meshcore reads what MeshCore sends in clear: header, path, and a
node's advert (name, kind, key, position)
- the list row, the details, a Capture's viewer and the console echo read
a packet by the sync word it was received on
- the bandwidth is printed as 62.5, not 62

WireGuard brings libsodium in unpinned. 1.10021.12 defines
crypto_sign_ed25519_open, as LibSSH-ESP32 does: a clean build failed with

The SSH App opens one session to a shell, over libssh (LibSSH-ESP32 5.10.0)
on mbedTLS. A server is trusted the first time on its fingerprint, and a
changed key is a warning with Cancel selected. The password is typed each
time and kept nowhere; or the device makes itself an Ed25519 key, whose
public half is shown, written to /ssh/id_ed25519.pub and printed by
`ssh status`.
lib/term is the terminal: what a shell, less, top, nano and vim send, with
sixteen colours, scroll regions, the alternate screen and 100 lines of
scrollback. Five text sizes with Ctrl and + or -, from 60x20 to 26x8, told
to the far end. The session goes on when the App is left; SSH shows in the
Status Bar. `ssh user@host` in the Shell opens the App.
Also:
- Keys that aren't characters carry Shift, Ctrl and Alt. The terminal needs
it, and it makes Ctrl+Fn+up/down in a note and Shift+Tab in Gemini work
from the real keyboard.
- IRC doesn't try to connect under 60 KB free: started with a session open,
its TLS handshake took the heap down to 236 bytes.
- libssh's own curve25519 is left out of the build (scripts/libssh_filter.py):
libsodium's has the same names.
Costs 292 KB of flash and about 50 KB of heap while a session is open; not
started under 75 KB free.
Docs: guide page, how-to, FAQ, home page, Status Bar, SD card folders, the
memory how-to, README, glossary, N1 notes with Q254 to Q266 and the checks.

The rest of the issue's list. tls makes a handshake that checks nothing,
then says the certificate in words: who it is for, who signed it, until
when, and whether this device's roots and the name asked for accept it,
with the reason when they don't. ntp compares a time server's clock with
the device's. netstat lists what listens and what is connected.

Network troubleshooting from the device itself, in the Shell and over both
consoles. ping, nslookup, port and traceroute each run on a task of their
own and print as they go, to the console that asked; one at a time, and
`cancel` stops it. ifconfig and arp answer at once: the interfaces (Wi-Fi
and the VPN), which is the default route, the DNS servers, the neighbours.
nslookup asks a DNS server itself, so it can say which server answered and
in how long, and ask another. A sized ping finds what a tunnel really
carries.
With a how-to, "When the network doesn't work", and the rest of the docs.
tls, ntp and netstat from the issue's list are not in this.

The documentation had kept up feature page by feature page and nowhere
else. Now also:
- the home page's App cards (notes of any size, pictures, sharing) and its
note (the Shell, the VPN, the screenshot key);
- the guide: VPN in the Status Bar and in Settings, the three keys that work
everywhere, screenshots of the Shell, a picture, sharing, the VPN page and
the help panel;
- three how-tos: move files with your phone, set up the VPN, take a
screenshot; where the files are and what things cost in memory;
- the FAQ: screenshots, and what listens on the network;
- the README's opening: what the firmware does today;
- the glossary: Tunnel, Sharing, Screenshot;
- every milestone's status line, with the version each thing shipped in.

The device joins a WireGuard network over whatever Wi-Fi it is on: one
peer, IPv4. A client's .conf is imported from the card (/vpn/wg0.conf) and
kept in the device's settings, private key included, never shown; Settings
offers to delete the file. A switch brings the tunnel up until the next
restart, "Start with Wi-Fi" every time; it waits for the clock, which a
handshake needs. VPN shows in the Status Bar.
The protocol is esphome/wireguard 0.4.8. It calls lwIP without lwIP's lock,
which this framework checks: every call into it is made with the lock held.
What goes through the tunnel is everything (AllowedIPs 0.0.0.0/0) or the
one subnet the device's tunnel address is in: lwIP routes by an
interface's subnet or by default, nothing finer. The import says how many
ranges it can't reach.
Checked against a test peer in both directions and against a real server,
with a configuration uploaded from a phone (docs/milestones/N1.md).

`w` in the Storage App starts a small HTTP server and shows its address,
as a QR code and in letters, with a six-digit code. A browser on the same
network that has typed the code can list, download, upload, make folders
and delete, under the Storage App's rules. The server runs only while that
screen is open. Nothing is encrypted, and the screen says so.
Uploads are streamed to the card under a temporary name and renamed when
whole. Every access to the card is handed to the storage task, 8 KB at a
time, from the server's own task.

Fn+p saves the screen as it is to /screenshots, as the Shell's `screenshot`
does, from anywhere: text fields, dialogs and the help panel included. The
key never reaches an App.
It refuses on Settings > Debug Console, which shows the token: a picture of
that page is a copy of the token in a file (App::showsSecret). `key shot`
presses it over the consoles.

Enter on a picture shows it: shrunk to fit the screen, or at its own size
with Enter again and the arrows to move. Dithered to the screen's 256
colours; a colour the screen has exactly is left alone, so screenshots are
shown as they are.
The picture is decoded once, straight into the screen's buffer, and kept
there (App::retainsContent): no copy in memory. Decoding runs on the
storage task, so the keys keep working and a 12 megapixel photograph
appears as it comes instead of tripping the watchdog.
PNG, BMP and GIF are read by decoders of our own, host-tested against files
made by Pillow; the PNG one needs 32 KB where the display library's needed
44 KB in one block, which the device often doesn't have. JPEG uses the
library's TJpgDec.
Also corrects two sentences that still gave 16 KB as the editing limit.

A search page whose index is the page itself: one item for each page and
each heading of the guide, the how-tos, the FAQ and the developer docs,
written by Zola from the pages' own content. A small script filters and
ranks them as you type. Nothing is fetched, so the Content-Security-Policy
needs nothing new; without JavaScript the page is a list of every heading.
The navigation gets a link, and the documentation's index pages a box that
is a plain form to /search/?q=. The devlog is not searched.

The editor held the whole note in memory and stopped at 16 KB. It now keeps
a window of the file around the cursor, and the rest on the card as a list
of pieces (notes::NoteDocument). Memory with a note open is what it was.
Up to 64 KB a save rewrites the file, as before. Above, the five-second
save appends what changed to <note>.edit, and the file is rewritten on
leaving the note, with a progress bar. After a power cut, opening the note
picks the edit up where it was saved; a rewrite cut short is finished or
dropped, never half applied.
Also: Ctrl with Fn+Up/Down go to the start and end of the note; the
consoles' `key` command takes ctrl-, alt- and shift-; the Storage App's
`e` no longer refuses a big file.

The Site workflow's last step, and the release workflow after publishing,
ask the web server over SSH to rebuild the site. The key CI holds is tied
on the server to one forced command (restrict,command=...), so CI sends no
command and a leaked key can only refresh the site. The server, the user,
the key and the server's host key are Gitea secrets; with none of them set
the step does nothing.
scripts/site_refresh.sh is what both workflows run;
scripts/site_deploy_keygen.sh makes the key and prints where each half goes.

Tab used to complete a command's first word only. It now follows the help
text word by word: `lora st` gives `lora status`, `gnss track ` lists
`start stop`. The words are read from the help text as written, so a new
command completes with no table to keep; the Shell's own words are added in
the same notation.
`*` and `?` in the last part of a path, for ls, du, rm, cp and mv, from the
Shell and both consoles. The command runs once for each name matched, lined
up and run by the main loop as each finishes; `cancel` empties the line-up.
64 matches at most, refused whole past that. In the Shell, rm with a pattern
asks once, with the count.
