/* asterconf.uz — shared styles for inner pages (/uslugi/, /asterconf-vs-*, etc.)
 *
 * Why a separate stylesheet vs. inlined-per-page?
 * - These pages don't need vanta.js or three.js (saves ~700KB per page).
 * - Sharing keeps brand colors consistent and one edit propagates.
 * - Browser cache: one fetch on first inner-page nav, free on every other.
 *
 * Variables mirror the landing's :root so colors stay 1:1 with index.html.
