   koolitarkus.ee — Digital Nebula Design System
   Single source of truth for ALL styles.
   design.md: "The Neon Oasis" — Y2K-revival aesthetic.

   Principles:
   - No-Line Rule: no solid borders, use glows/tonal shifts
   - Ambient Luminescence: shadows tinted with accent
   - Glassmorphism: frosted glass on floats/modals
   - Mobiil-first, 375px tested
   - Dark mode primary, light mode secondary
