 * The rules of a grid of drawings (`drawGrid`): the ground colour and the quiet ink of the subtitle and the credit line in light and dark, and the classes of the
 * title, the subtitle, a cell's label, the key and the credit line. A grid is a `.kyogijo` as well, so the base rules give it the ink, the font and the colours of the
 * layers; `KYOGIJO_STYLE` has these for a page that draws with `style: "none"`.
