+## Docker Image Guidelines
+
+When updating Docker image references in `docker/Dockerfile` or other container files:
+
+- **Always use multiplatform/index digests**, not architecture-specific digests
+- Architecture-specific digests (e.g., for `linux/amd64` only) will cause CI failures on different build environments
+- On Docker Hub, the multiplatform digest is shown on the main image page, while architecture-specific digests are listed under "OS/ARCH"
+- Example: Use `node:20.20-bullseye-slim@sha256:abc123...` where the digest is from the multiplatform index, not from a specific OS/ARCH variant
+
