Site: the user guide (phase 2): the basics, one page per App, Settings and Updates

Eleven pages under /guide/, written from the README, the milestone documents
and the Apps' own source: the keys, the Launcher, the Status Bar and the first
start; the LoRa Scanner, GNSS, Gemini, IRC, Wi-Fi tools, Notes, Storage and
System; Settings (with Wi-Fi) and Updates. Real screenshots where the site has
them, a Guide link in the navigation, and the home page points to it.

+
+The Wi-Fi tools show what the radio hears **now**: they scan for the networks around you and list them. They do not join anything.
+
+## The menu
+
+Three entries: **Networks nearby**, **Channel occupancy** and **Signal tracker**. Pick one with the arrows and press <kbd>Enter</kbd>.
+
+## Networks nearby
+
+A list that refreshes by itself: each network's name (or `(hidden)`), channel, signal in dBm and security. The top line says how it is sorted and filtered.
+
+| Key | Does |
+|---|---|
+| <kbd>s</kbd> | Sorts by signal, channel or name, in turn |
+| <kbd>o</kbd> | Shows only open networks |
+| <kbd>h</kbd> | Hides the hidden networks |
+| <kbd>w</kbd> | Shows only the strong ones |
+| <kbd>l</kbd> | Starts and stops **logging** |
+| <kbd>Enter</kbd> | Opens the **Signal tracker** on that network |
+
+**Logging** adds each scan to `/wifi/scans/<date>.csv` on the SD card, one row per network, once the device knows the date; `LOG` and a row count show while it runs. Logs stop when the card passes 90% full.
+
+## Channel occupancy
+
+One bar for each of the 13 Wi-Fi channels shows how busy it is: how many networks use it, and how strong they are. The top line counts the networks and names the quietest of the three channels that don't overlap, **1, 6 and 11**. It is the quick answer to "which channel should my router use?". <kbd>`</kbd> (Back) returns to the menu.
+
+## Signal tracker
+
+Follows one network: its name, address and channel, then the signal in dBm in large type, a strength bar, and a graph of the recent readings, so you can walk towards the strongest signal. <kbd>m</kbd> turns audible clicks on and off. If the network is no longer heard the screen says `lost`. <kbd>`</kbd> (Back) returns to the list.
