/* Kids Menu. REFERENCE: a diner kids' menu on a checkered tablecloth.
   COMMITMENT: a faint red-and-white diner tablecloth; the menu sits on it as real paper.
   Everything on the paper is pure black on white (Jeff's B&W laser prints grey as fuzzy
   dots), so the screen shows exactly what prints. One radius for UI (12px); the menu
   cards use the rounded diner look. Fredoka for the menu, Archivo for the controls,
   Comic Sans for the famous game (Comic Neue where a device has none). */
