- lib/wifi (host-tested): SavedNetworks (up to 8, validated, hidden
flag, persisted) and WifiController (joins the strongest Saved
Network, tries hidden ones in turn, backoff 10/30/60 s, connect
timeout, Monitoring override, radio off without Saved Networks)
- WifiService carries out the controller's actions, sets the EU
country code, and syncs the Clock over SNTP without touching the TZ
- Wi-Fi On/Off setting; Settings > Wi-Fi page: status, add from a scan
or a hidden network, forget
- Status Bar: W + signal bars, W? while searching, MON while monitoring
- Serial: wifi add / wifi status (replaces the step 1 heap probe)
Verified on the device: joins the test network ~5 s after boot, clock
set over NTP, ~129 KB free heap while connected.
