Me Here af8e7e236b PM_K-1 hardware: render simulations as PNG plots (gnuplot) so they're viewable
Added gnuplot to the EDA container; sims now wrdata their curves and plots.gp renders 5
PNGs in hardware/eda/sim/plots/ (open in any browser/viewer):
- input_loading: instrument(1M) preserves the +16dB pickup resonance the line(25k) flattens
- stage1_cmrr: common-mode leakage, 0.1% vs 1% resistor mismatch
- stage2_recon: DAC reconstruction filter (flat to 20k, -3dB ~75k)
- stage4_driver: balanced differential response (flat across audio)
- stage1_phantom: +48V transient clamped at the op-amp input, decays to ~0
(.data intermediates git-ignored.)

# Reproducible EDA toolchain for the PM_K-1 core board.
#
# Why this exists: the system KiCad is 7.0 (no CLI ERC). This pins a known,
# rebuildable environment so the design can be checked/simulated identically
# years from now — fitting for a device meant to outlive its tools.
#
# KiCad 9 -> schematic capture, CLI ERC/DRC, netlist/PDF/Gerber export
# ngspice -> SPICE simulation of the analog audio circuits
# python3 -> scripting / BOM / skidl-style helpers
#
# Build/run via ../eda/run.sh (or: podman build -t pmk1-eda:9.0 .)
