/**
 * Page-specific styles for /printable-rules.
 *
 * Companion to /css/entry/content.css, which provides article
 * typography (headings, tables, lists, figures rendered inside each
 * .pr-card__body). This file owns the surrounding layout — header,
 * sticky controls, quick-nav grid, game cards, and the single-game
 * print mode.
 *
 * Selectors use the .pr- page namespace to avoid colliding with the
 * sibling chrome/pages/*.css files (brain-games, mahjong-games,
 * library, all-games, all-guides), all of which use bare
 * .filter-btn / .game-card / .page-header / etc. selectors. Keeping
 * this page namespaced means it doesn't add to the Phase-5 cleanup
 * backlog and doesn't increment .css-audit-budget.json totalDupes.
