# Stage 1: build the React SPA.
# Pin to the native build host ($BUILDPLATFORM) so the Node/V8 build never runs
# under QEMU during multi-arch builds — emulated Node crashes V8's baseline JIT
# (SIGTRAP / exit 133 on `npm ci`). The dist/ output is static JS/CSS, i.e.
# architecture-independent, so building it once and COPYing it into each
# target-arch runtime stage is both correct and avoids the emulator entirely.
