# layers (~10GB). The worker runs `node dist/.../index.js`, which resolves
# @alga-psa/* via node_modules -> packages/*/dist, and does NOT load server/
# (build-time type imports only) or the UI/build libs. Copying the final /app
# into a clean stage drops the intermediate layers; removing server/ source
# reclaims ~2GB more.
