# INBUXA Admin as an image: the built interface and a static server for it.
#
# The interface is static files and nothing else -- it talks to the mail server
# from the browser, never from here -- so this is nginx with a SPA fallback and
# no back end of its own.
#
# It is built here rather than copied from `dist/`, which is committed for the
# convenience of people serving the tree directly. An image built from a stale
# `dist/` would be a build nobody can reproduce from the commit it claims.

# The lockfile alone first, so a commit that changes no dependency reuses this
# layer instead of resolving the tree again.
