Prototype fabrication release generated from diode-vca-attenuator.kicad_pcb.

Upload only the copper, solder-mask, top silkscreen, edge-cut and Excellon drill
files in this directory unless the chosen fabricator explicitly requests more.
The rules (0.25 mm minimum track, 0.20 mm clearance, 0.60/0.30 mm vias) are
provisional design tests and have not been approved by a fabricator.

Final KiCad 10.0.6 result: 0 DRC errors, 0 unrouted, one isolated-copper-fill
warning, zero exclusions. See ../../reports/drc-raw.json and check-summary.md.
