# Pin the build stage to the native build platform so Hugo runs once (never
# under QEMU emulation). Hugo output is static HTML — identical across arches —
# so there's no reason to run it per target arch. The runtime stage below stays
# on TARGETPLATFORM, so multi-arch (amd64 + arm64) runtime images are preserved.
