/* 天津狗不理包子 Restaurant OS: 茶記水牌 (cha chaan teng menu board).
   Cream paper, diner green, red prices, yellow stickers, 2px ink rules.

   round only for stickers and stamps. Primary buttons sit on a 4px ink ledge.
   Light only: the brand is printed paper. The kitchen screen sets its own green board. */
