Building notes
If you get an error upon attempting to build that looks like:
"multiple platforms feature is currently not supported for docker driver",
check the output of docker buildx ls.
You may need to switch to a different builder, which you can create by:
docker buildx create --name buildx-container --driver=docker-container
Then during building, specify the builder buildx-container. For example:
just build-commit buildx-container.
