Second row in the Config view: UP/DOWN moves focus between Min dist and Units, LEFT/RIGHT cycles the focused row's value. Units propagates to the Summary view, which now shows either "Avg: N km/h" / "N mph" or "Pace: M:SS /km" / "/mi" depending on the choice. Pace renders as "--:-- /unit" when distance or elapsed time is zero (avoids divide-by-zero glitches with one-point trails). mph conversion uses the 0.621371 ratio with rounding; pace works in floating point off raw metres and seconds for accuracy at low speeds. NodePrefs gains trail_units_idx as another reserved-ish byte; old saves load with 0 = km/h, no schema bump needed since the rd() lambda already defaults missing fields to zero.
