   auth-scene.css -- login, signup, forgot-password, reset-password

   Yeh chaaron page theme.css ke token par chalte hain. Yahan sirf
   layout aur baayein taraf ka drishya hai.

   DRISHYA KE BARE ME
   ------------------
   3D three.js se NAHI banaya. three.js ~600KB ka hai aur mobile ki
   battery khata hai; hamare zyadatar users phone par hain. Yeh sab
   CSS perspective + transform se hai -- lagbhag 0KB, aur gehrai ka
   wahi ehsaas.

   Teen niyam ismein pakke hain:
     1. Mobile par drishya band. Chhoti screen par wo jagah gher leta
        aur form neeche chala jaata.
     2. prefers-reduced-motion par sab ruka. Yeh sirf niyam nahi --
        kuch logon ko hilti cheezon se sach me chakkar aate hain.
     3. Panel me nakli graphic nahi. Wahi cheezein hain jo login ke
        baad milengi.
