/*
 * ArtUp AR XR — shared design system for the product landing (/ar-xr/) and the demo app
 * (/ar-xr/demo/: catalog, viewer, XR UI). Standalone: no @import, no external fonts or CDNs.
 * Same visual language as the company site (/style.css): system font, blue accent #0b5cd5
 * (dark #6ea8ff), radius 10px, light + dark via prefers-color-scheme; AR XR adds a blue→violet
 * gradient (--ax-grad) for hero, icon and primary emphasis.
 *
 * Theme: follows the OS by default. Force a theme with <html data-theme="light"> or "dark".
 *
 * Everything is namespaced with "ax-" so it can sit next to existing demo CSS without clashes.
 *
 *   Page base     .ax-page (on <body>) — background, font, links. Optional: demo pages may skip it.
 *   Layout        .ax-container  .ax-section  .ax-section-soft  .ax-grid (+ .ax-grid-2/-3/-4)
 *   Header        .ax-header > .ax-container.ax-header-row > .ax-brand + .ax-nav + .ax-header-actions
 *                 .ax-brand: <a class="ax-brand"><img class="ax-brand-mark"> <span class="ax-brand-name">…
