* Seed Site Planner params from a node (name + position) and, when a radio is connected, from its actual config:

* transmit frequency (from the primary channel), transmit power (dBm→W), and a receiver sensitivity derived from the

* modem preset. Antenna gain/height aren't in the device config, so they keep the planner's stock defaults.

*

* Flavor-neutral: both the Google and F-Droid maps feed the same hosted Site Planner.
