webd-iitbbs/gymkhana-iitbbs — reverse-engineered prompt

Build me a simple website for the Students' Gymkhana of IIT Bhubaneswar. It should feel like an official student body site where visitors can quickly learn about the Gymkhana, its office bearers, facilities, clubs, fests, sports, cultural activities, technical activities, and major events like sports meet and tech meet.

I want a clean home page with navigation to all main sections, separate pages for cultural, technical, sports, facilities, fests, contact, and office information, plus pages for clubs and student councils if needed. Keep the design straightforward, responsive, and easy to update later.

Please also add a basic admin login area so authorized people can manage or update site content without touching the code. Use PHP since this looks like a PHP project, and keep the setup simple enough to run on a normal college web hosting server. Make sure the contact page and navigation work properly.
