Auto/Manual DC Power-Window Controller
Verified interactive simulator - schematic and solver share one netlist
(src/core/netlist.ts). A = + runs DOWN (close), B = + runs UP (open).
Rain + clear beam energises K1, which transfers the motor off the DPDT and
closes the window from any switch position.
