   RANG — SIRF YAHAN
   Asool (docs/DECISIONS.md, hissa 6.1): koi rang kisi aur file mein hardcode nahi.
   Sab yahan tokens ki shakl mein. Ek jagah badla, poore software mein badal gaya.

   Teen halaat:
     :root                              → light (buniyad)
     @media (prefers-color-scheme:dark) → computer ki setting dark hai
     [data-theme="dark"] / ["light"]    → user ne khud chuna (ye sab par bhaari hai)
