// Network & Devices.
//
// Wi-Fi and Bluetooth are handled here rather than delegated. Everything goes
// through Quickshell.Networking and Quickshell.Bluetooth -- NetworkManager and
// BlueZ over DBus -- and nothing shells out to nmcli or bluetoothctl. That was
// the founding requirement for this desktop: never having to drop to a terminal
// to join a network.
//
// Scanning follows this page being on screen. Wi-Fi scanning and especially
// Bluetooth discovery hold the radio, and doing either for a list nobody is
// looking at is battery and airtime spent on nothing.
