      # vendor/ is kept in a named volume to avoid stale host-installed packages
      # breaking the container (e.g. wrong PHP version). The container runs
      # "composer install" automatically whenever vendor/ is missing or empty.
      # To use a local vendor/ instead (e.g. for IDE autocomplete), remove this
      # line and run "composer install" on the host — the container will use
      # whatever is on disk and skip reinstalling if autoload.php is present.
      - 'opendominion-vendor:/var/www/html/vendor'
      # Same rationale as vendor/ — node_modules/ is isolated to prevent host
      # yarn runs from polluting the container, and yarn --frozen-lockfile is
      # used to ensure an exact install from yarn.lock. Remove this line to use
      # a local node_modules/ instead (requires running "yarn install" on the host first).
