/* ==========================================================================
   DESIGN SYSTEM — token & komponen bersama halaman design-v2
   --------------------------------------------------------------------------
   Dimuat SEBELUM landing-v2.css / course-detail.css. Token didefinisikan
   pada :root (terang) dan html[data-theme="dark"] (gelap) sehingga bisa
   dipakai semua halaman yang memakai kelas body `design-v2`.

   Cara pakai di view PHP:
     $bodyClass = 'design-v2 page-xxx';
   Cara muat di header.php:
     if (str_contains($bodyClass, 'design-v2')) load design-system.css
