/* HouseChalk patterns.
 *
 * THERE IS NO PATTERN. The blueprint grid is gone: it competed with every
 * surface it sat behind, it forced page grounds to set background-COLOR rather
 * than the shorthand or silently lose their texture, and on a dense screen it
 * added a third thing for the eye to resolve before reading a word. The surface
 * ladder does the work the grid was decoration for.
 *
 * What remains is the page ground behind a drawn frame, and the well a document
 * sheet rests on. Nothing here is a texture. */
