 * CUSTOMISING FOR YOUR SITE
 * ─────────────────────────
 * Override CSS variables inside your theme stylesheet:
 *
 *   .wl-wrap {
 *     --wl-bg:      #ffffff;   ← game background
 *     --wl-surface: #f8f8f8;   ← card/panel background
 *     --wl-text:    #111111;   ← main text colour
 *   }
 *
 * Override individual components by targeting the same
 * scoped selector in your theme CSS, e.g.:
 *
 *   .wl-wrap .wl-logo { font-family: 'Your Brand Font', serif; }
 *   .wl-wrap .wl-btn-primary { background: #your-brand-colour; }
 *
 * Game-specific variables (colours, radii, transitions) are
 * all listed in the :root block of .wl-wrap below.
