/* ==========================================================================
   Kausol — landing page styles
   Layout: fonts → tokens → base → hero → constellation map → CTA →
   horizon (planet) → contact → footer → responsive → reduced motion.
   Motion policy: continuous animations only touch compositor-friendly
   properties (transform, opacity); hover effects are gated behind
   (hover: hover) so they never stick on touch screens; everything stops
   under prefers-reduced-motion.
