# Stage 1: frontend — built once on the native build platform (the output is
# static JS/CSS, so it doesn't need per-target emulation). Vite writes into
# ../internal/webui/dist.

# Stage 2: Go binary (embeds the built frontend + openapi.yaml). Runs on the
# native build platform and cross-compiles to the target, avoiding QEMU.
