/* Notley Piano.
   A dark stage, like a concert hall with the lights down: ebony surfaces, ivory text, a felt-red accent and brass for Premium.
   Everything blends: no boxed navigation, no outlines around sections. Song covers carry the colour.
   Sheet music sits on warm paper, the one bright surface, because that is what you read music from. */
