/* ============================================================
 * docs.css — layout + theme for every page on docs.wintersalmon.com
 * ============================================================
 *
 * The page contract (enforced by `bun run docs:check`, described in
 * /_guide/index.html):
 *   - every page links this file and ../_theme/docs.js by RELATIVE path, so a
 *     page opens the same from file:// and from the deployed site;
 *   - docs.js always sets <html data-theme="light|dark"> ("auto" resolves to
 *     the OS preference), so this sheet and each game's generated tokens.css
 *     both key off [data-theme] and can never disagree;
 *   - game colours come from the game's own tokens.css, loaded after this
 *     file. The chrome below only uses --wf-* so a game palette never leaks
 *     into it.
 *
 * Components keep the wf-* class names of the old wireframe shell, so pages
 * move here without rewriting their markup.
 * ============================================================ */
