/* The kitchen display.
 *
 * Read from six feet away, in a room that is hot, loud and bright, by
 * somebody holding a pan. Every choice here follows from that: very large
 * type, few colours, no hover states (nobody hovers on a wall tablet), and
 * touch targets a knuckle can hit.
 *
 * Deliberately its own stylesheet rather than the portal's. The portal is a
 * desk tool with tabs and tables; this is one screen with one job, and
 * sharing components would drag one of them toward the other. */
