# Install Python/NodeJS dependencies before copying code to limit download size
# when code changes.
#
# Note that we also have to copy the `packages` directory so that `yarn`
# can resolve the workspaces inside it and set up symlinks correctly.
# This is suboptimal, as a change to any file under `package/` will
# invalidate this layer's cache, but it's unavoidable.
#
# We also need to copy both the `.yarn` directory and the `.yarnrc.yml` file,
# both of which are necessary for Yarn to correctly install dependencies.
