# ---- Stage 1: Build ----
# Always runs on the machine's own platform, never emulated: the standalone
# output is plain JavaScript (the only native module traced into it is sharp,
# which NasDash never loads since it does not use next/image). Multi-platform
# images then only assemble the runner stage per platform, instead of
# building the whole app under QEMU (about 8 minutes for arm64).
