## Overview

BLITZ is a frontend platform for Dibrugarh University’s coding club: visitors browse club events and profiles, students can sign up, and admins manage club content. The README describes a current localStorage prototype and a separate planned API, database, media-storage, and JWT architecture. Only the README is present in the supplied tree, so implementation paths and undocumented wiring cannot be verified; planned integrations are shown as optional.
