        # It's intended to be used only on development. For production, you
        # should use the rack handler command directly (i.e. `bundle exec puma
        # -C config/puma.rb`).
        #
        # The server is just a thin wrapper on top of Rack::Server. The options that it
        # accepts fall into two different categories:
        #
        # - When not explicitly set, port and host are not passed to the rack
        # server instance. This way, they can be configured through the
        # configured rack handler (e.g., the puma configuration file).
        #
        # - All others are always given by the Hanami command.
        #
        # Run `bundle exec hanami server -h` to see all the supported options.
