1 = single-layer winding (the whole slot is one coil side). 2 = double-layer winding
(two independent coil sides share the slot). Just a multiplier on total copper area here —
doesn't model which physical half of the slot each one occupies.

Correction factor = measured ÷ predicted at the same temperature. When applied, it
scales every DCR value below (main result and sweep table) — the underlying formula
itself is unchanged.

A separate utility — take any known resistance (R1/T1 default to the result above) and
find its value at a different temperature (T2). Not part of the geometry calculation.
