/* Video-call UI.

   Pehle ye poori dark thi. Wajah wajib thi - camera feed ke aas-paas light
   chrome aankh mein chubhta hai. Par asli istemaal mein poora screen kaala
   pad jaata tha aur labels, buttons, timer sab padhna mushkil ho gaya.

   Ab beech ka raasta: chrome (panel, button, text) light hai taaki sab saaf
   dikhe, aur camera ke tile abhi bhi dark hain - wahan video ke chaaron taraf
   safed border achha nahi lagta. Tile ka background neeche hardcoded hai
   (#0e1013), isliye palette light hone par bhi wo dark hi rehte hain.

   Dhyan rahe: jin jagah background hardcoded dark hai, wahan text ka rang bhi
   fix karna padta hai - warna light palette ka gehra text kaale par gayab ho
   jaata hai. */
