# Targeted (re)build of specific package versions, executed on a remote buildx
# builder. The build's effect is the S3 upload performed by build-one.R; no
# image is kept (the justfile uses --output type=cacheonly). CACHEBUST forces
# the RUN to re-execute on every invocation.
#
# Build context is `local/` (see the `rebuild` recipe in the justfile).
