   Yatra Booking — Passenger portal styles
   Navy + gold theme (matches the passenger mockups). Structural patterns
   (badges, modal, toast, forms, skeletons) mirror ../operator/css/operator.css
   and ../admin/css/admin.css so class names behave the same way for the
   shared/js helpers (toast(), openModal(), badge(), skeletonRows()).
