"""GND stitching vias on a grid (spec.stitchVias as explicit {net,x,y} points), each spot checked against the LIVE copper the
same way as the heatsink vias (gen/tvias.py): inside the GND outer pour on both outer layers (so outside every other pour and
its clearance), clear of every other net's live track, via and pad, hole-to-hole 0.28 mm from every drill. Via 0.6/0.3.
Pitch 8 mm (spec stitchVias.GND.pitchMm); a spot that fails moves on a 0.5 mm search around its grid point."""
