Why

scripts/build.sh ran buildx create --use with the default docker driver, which can't do multi-platform builds or --cache-to type=registry exporters that the README advertises.

What

Create the builder with --driver docker-container (+ binfmt/qemu setup for multi-platform). Note: no docker on the dev box, so validated by lint; buildx exercised by CI runner.

Testing

shellcheck/lint pass. Backlog rank 7.
