# Build ngspice_service.{js,wasm} — the eeschema simulator's ngspice worker
# module (wasm/ngspice-service/). Unlike occ_service this does NOT go through
# the kicad CMake tree: the module contains no KiCad/wx code, so it configures
# standalone against the sysroot ngspice artifacts (much faster to iterate,
# and buildable without the full editor dependency set).
#
# Artifacts: ${BUILD_ROOT}/kicad-ngspice_service/ngspice_service/ngspice_service.{js,wasm}
# — the kicad-<app>/<subdir>/ layout every other app uses, so docker/build.sh's
# output copy and tests/scripts/setup-kicad-wasm.sh's docker-volume fallback
# find them without special-casing.
