Me Here fb9afe2b27 PM_K-1 hardware: custom TQ2SA relay footprint (verified) + project fp lib
hardware/kicad/pm_k1.pretty/Relay_DPDT_Panasonic_TQ2-SA.kicad_mod -- built from the
Panasonic TQ-SMD datasheet "Recommendable mounting pad, SA type" (2.54mm pitch, 1.0x2.94mm
pads, rows +/-3.31mm, pin map coil 1/10 / pole1 COM3 NC4 NO2 / pole2 COM8 NC7 NO9).
Validated via `kicad-cli fp upgrade` (parses to canonical KiCad 9 format). board.py now
references pm_k1:Relay_DPDT_Panasonic_TQ2-SA and pm_k1:RV-8803-C7.

RV-8803-C7 footprint NOT built: every host with its land pattern blocks/times-out my
fetcher (Micro Crystal, EM Micro, Mouser) and SnapEDA needs login. Won't guess a 0.8mm-pitch
land pattern (geometry + pin-pad mapping). Drop a verified RV-8803-C7.kicad_mod into
pm_k1.pretty (SnapEDA / datasheet) and it resolves.
