Sidharth VinodandClaude Opus 5.5 5eedbbecfa ci: Build the Docker image's static site natively instead of under QEMU
The multi-platform Docker build ran pnpm install and pnpm build for
linux/arm64 under QEMU emulation. QEMU intermittently crashes there
("qemu: uncaught target signal 4 (Illegal instruction)") or stalls, and
buildkit then waits until GitHub cancels the job at 6 hours: 16
cancelled runs in September, including a develop push.

The build output is a static site, identical on every architecture, so
the node stages now run on $BUILDPLATFORM and only the nginx stage
(COPY only) is built per architecture. Also caps the job at 30 minutes
so any future hang fails fast.
