   -----------------------------------------------------------------
   Plain, framework-free CSS for the Golf Simulator Booking System.

   HOW TO INTEGRATE INTO YOUR EXISTING SITE:
   - Everything is namespaced under a small set of class names
     (.gb-*) and CSS custom properties (variables), so it shouldn't
     clash with your existing site's classes.
   - Just change the values in the :root block below to match your
     site's fonts / colours - the main accent colour requested is
     already set to #f6192b.
   - If your site already has its own <body> font/background, feel
     free to delete those two rules and inherit from your theme.
