A team's CI pipeline builds an image successfully, but the exact same Dockerfile fails to build on a developer's laptop with a 'no space left on device' error.

This points to local Docker disk usage exhaustion (cache, old images, dangling layers accumulated over time) rather than a Dockerfile problem — diagnose with `docker system df` to see space breakdown, and resolve with `docker system prune -a --volumes` (after confirming nothing important would be lost), or by increasing the Docker Desktop VM's allocated disk size on macOS/Windows.
