/* Paint chips: the autumn colour card of a made-up paint maker, in the minimal style. A warm white page, black ink and
   six paint colours. In a tall section a stage stays still while you scroll: on it a row of tall, narrow chips. Every
   chip is a layer as big as the stage, cut down to its strip by a clip-path that the script writes; inside it the
   script adds the big name, a hairline with a note and the colour code, and a copy of the header in the colour that
   reads on the paint. */
