/* Tab pill-bar: agar 4 tabs + notif + home + logout ek line me na aayen,

   CRITICAL FIX: .tabs ek flex-child hai (.header-right ke andar), aur
   flex-children ka default "min-width: auto" hota hai — jiski wajah se
   browser ise kabhi shrink hi nahi hone deta tha, isliye overflow-x:auto
   kaam nahi kar raha tha aur "Admin" tab bas cut/clip ho raha tha, scroll
   nahi ho raha tha. min-width:0 dene se ab yeh sahi se shrink + scroll
