/* Vultify shared UI layer ("vx") — the single source of truth for page chrome
 * on all non-divergent pages. Loaded AFTER styles.css:
 *   <link rel="stylesheet" href="/static/styles.css?v=...">
 *   <link rel="stylesheet" href="/static/ui.css?v=1">
 * It reuses the :root tokens from styles.css (--bg0..--bg2, --line, --text,
 * --muted, --accent, --accent2, --ok, --warn, --danger, fonts) and defines the
 * canonical versions of the component classes the pages already share
 * (header/.brand/nav, .grid, .card, .row, .pill, .btn, inputs, tables...),
 * so pages can delete their local copies. Page-specific extras stay in the
 * page's own <style>. Divergent pages (index/trading/ecosystem/status) do not
 * include this file and are unaffected.
