- Placement script (layout_pcb.py): LV left, HV right, panel connector on the
boundary, terminal blocks on the edges, heatsink space for the TO-220s
- Freerouting-based routing script (route_pcb.py) that routes with oversized
tracks/vias and shrinks them, giving 3 mm HV-to-LV and 1.3 mm HV-to-HV
- Custom DRC rules (plasma_dmd_psu.kicad_dru) with documented exceptions
- Wide TO-92 footprints; schematic generator now keeps symbol UUIDs
- DRC: 0 violations, 0 unconnected pads, schematic parity OK
