  # Separate mix project, not a dependency of `ankusa`'s own mix.exs. This is the
  # forced split point from the packaging decision: `ankusa` core stays
  # zero-external-dep (compiles for the laptop/standalone user without ever
  # touching postgrex); this package exists only for deployments that opt into
  # a shared Postgres WAL. Path-dep on `ankusa` for development; becomes a normal
  # Hex dependency once both are published.

  # entries for the same app regardless of :only, so this has to be a
  # single conditional entry, not a duplicate-with-disjoint-:only pair.
