/*
 * Brass landing page (apex brass.build). Self-contained: this page is a
 * separate marketing surface from the dashboard SPA (app.brass.build), so
 * it carries its own copy of the brand tokens + the two self-hosted
 * variable fonts rather than importing the dashboard's bundle.
 *
 * The look is a dark, premium "brass + desert light" treatment: a warm
 * radial glow on a near-black field, with the faceted pyramid mark as the
 * single bright object.
