/* Contact us page (/contact).
 *
 * Built on auth.css (the aurora stage, glass card, fields and gold button of
 * the sign-in pages) and theme-dark.css; this file adds the hero, the service
 * chips, the contact-detail cards, the map and the enquiry form's extras.
 *
 * Layout, mobile first: hero, detail cards, form, map in one column. From
 * 1024px the cards and the map share the left column and the form sits on
 * the right; a page without details or map shows the form alone, centred.
 * Motion: a staggered rise on load, a soft pulse, hover lifts. Only transform
 * and opacity are animated and everything stops under prefers-reduced-motion.
