/* File: shared/css/landing.css
 *
 * Landing page for the ECVALLA Ticket System.
 *
 * Purpose-built rather than a variation of the old systems gate: the platform is now a
 * single product, so the page has one job — say what this is and get the visitor either
 * signed in or into the ticket form.
 *
 * Structure: an ink canvas carrying the existing site video as desaturated texture, a
 * wordmark bar, a hero, three plain statements of how the flow works, and a quiet footer.
 * Type does the work — the identity's tight display tracking against wide-tracked
 * micro-labels — so the page stays calm at any width.
 *
 * Tokens come from ecvalla-identity.css, which is loaded before this file.
