/*!
 * CheckrideReady Marketing/Doc Layer
 * ==================================
 * Shared partial for the checkride-prep / ACS guide article pages
 * (private-pilot-checkride-prep.html, instrument-rating-checkride-prep.html,
 * commercial-pilot-checkride-prep.html, faa-acs-guide.html).
 *
 * Requires tokens.css, base.css and components.css loaded first (see the
 * README in this folder for the full load order). This file adds:
 *   1. the mobile nav panel behavior for `.site-nav-toggle` / `.site-nav-links`
 *      (components.css defines their base/desktop styles but not the
 *      open/closed mobile panel -- that lives here since it's specific to
 *      how these four pages wire up their toggle)
 *   2. the article/doc content styles (breadcrumb, answer box, headings,
 *      FAQ accordion, cross-link cards, code callout, CTA box)
 *
 * These four pages previously carried four byte-identical copies of a
 * 60-line <style> block that redefined :root tokens already owned by
 * tokens.css. This file replaces all four copies with one.
