Summary

  • add a parameter-driven LGA model for Footprinter's new lga primitive
  • generate perimeter contacts from the parsed grid, pitch, package, and pad dimensions
  • wire and export the model, add a Cosmos example, and commit a PNG regression snapshot
  • bump @tscircuit/footprinter to ^0.0.391

Why

Configurable LGA footprints currently render without a package body. This adds the missing package, perimeter contacts, and pin-1 mark while respecting non-square grid definitions.
