/* word-search/style.css
 *
 * Loaded after the site stylesheet (/style.css) and subordinate to it, on
 * the same three rules as solitaire/style.css:
 *
 *   1. never redefines a selector the site defines (.btn, the modal and
 *      settings components, .site-header/.site-footer, .achievement-toast);
 *   2. no bare element selectors;
 *   3. every selector is a .ws- class or scoped under #word-search.
 *
 * Palette: the site's :root custom properties, plus what a paper sheet on
 * a felt table needs and the site has no name for — the paper tones, the
 * hairline rule, the two textures, and the eight pastel capsule colours.
 * They are declared once, on #word-search.
 *
 * Sizing: every grid dimension derives from --cell, which main.js sets on
 * .ws-board from the measured width (n cells must fit the sheet), together
 * with --n, --letter and the panel paddings. Nothing here is sized from a
 * media query alone.
