/**
 * site.css - shared theme, nav, button, section-shell, and contact/footer
 * styles for every page on lgcarrell.com (the home page and every game
 * page under /games/). Extracted verbatim from the home page so every
 * page matches exactly rather than approximately.
 *
 * A page still has its own <style> block for content that's genuinely
 * page-specific (the home page's hero/case-study/lightbox CSS, a game
 * page's puzzle/account-bar CSS). This file only holds what's shared.
 * Load this BEFORE a page's own <style> block so page-specific rules can
 * still add to or override a shared selector (e.g. a page adding its own
 * padding to .wrap) without fighting CSS cascade order.
