/* MCQIndia JEE - theme
 *
 * Matches the CBSE, Olympiad and main-site pages: same palette, fonts, logo,
 * header, cards and dark mode. The JEE pages are Bootstrap 5.3 markup, so this
 * file works by (1) setting the site tokens, (2) pointing Bootstrap's own
 * variables at them and (3) restyling the components the pages use.
 * Dark mode follows the visitor's system setting (templates/header.php sets
 * data-bs-theme on <html>).
