/* crossword.css — /crossword/ (docs/crossword-plan.md).
 *
 * Built for a seven-year-old on a Chromebook or an iPad first, and a phone
 * second. FULL WIDTH: no narrow centred column (the house rule). The page is
 * a column of the viewport's height — header, the play area (which scrolls
 * if it must), and the keyboard pinned to the foot — so the keys never move
 * and nothing scrolls sideways.
 *
 * Colours come from the site's tokens (readflexes.css) plus a few of this
 * page's own, defined for dark and for light. A mark is never colour alone:
 * a wrong letter also carries a slash, a given one a dot.
