/* ============================================================================
 * Grace Arena Fitness — Design System v2 ("Premium")
 * ----------------------------------------------------------------------------
 * Goals: modern, polished, trustworthy. Mobile-first. No framework, no web
 * fonts (stays offline-capable & fast on Opera Mini / low-end Android).
 *
 * Every class name and CSS variable used by js/app.js is preserved, so this is
 * a pure visual upgrade — no JS changes required.
 *
 * (Optional) For an even more "designed" feel you can add Inter:
 *   <link rel="preconnect" href="https://fonts.gstatic.com" crossorigin>
 *   <link href="https://fonts.googleapis.com/css2?family=Inter:wght@400..800&display=swap" rel="stylesheet">
 *   then set  --font: 'Inter', system-ui, ...  below. (Not done by default to
 *   keep the app fully offline.)
