   Kawan Labs — site stylesheet (1.3 redesign, "Kawan Studio")

   Design system (UI/UX Pro Max, verified for this product: an app studio catalog):
     style    Minimalism & Swiss Style — white space, hairline borders, grid-based, high contrast
     pattern  Hero + Features + CTA — split hero with a three-phone showcase, catalog, principles, contact
     type     Plus Jakarta Sans (single family, self-hosted variable font, OFL)
     colour   neutral slate base · one deep-blue brand accent · each app's colour only as a soft tint;
              light + dark: follows the OS by default, or the visitor's choice (System / Light / Dark)
              from <html data-theme>. Every text pair meets WCAG AA (4.5:1) in both.

   No JavaScript anywhere: the catalog filter is radio inputs + :has(); the theme switch is three links
   handled by nginx (cookie → data-theme); reveal motion is a CSS scroll-driven animation behind
   @supports and prefers-reduced-motion.

   One source of truth per colour: light-dark(<light>, <dark>). Which side applies follows `color-scheme`:
     <html> without data-theme, or data-theme="system"  → color-scheme: light dark → the OS setting
     <html data-theme="light">                           → color-scheme: light
     <html data-theme="dark">                            → color-scheme: dark
