# Build the dsv41-flash B12X wrapper (thin FROM over the sm121-built base).
#
# Uses the classic docker builder (not buildx docker-container): the base
# image dsv41-flash:local is local-only (never pushed to a registry), and
# the container-driver builder cannot resolve local FROM references.
#
# Generic driver: forwards every KEY=VAL pin in versions.env as a
# --build-arg to the Dockerfile (no hardcoded variable list). The sm121
# launcher writes a merged versions.env here when a recipe carries
# [build.versions] overrides (recipe wins over the image defaults).
