## Overview

NLAMS is presented as a national land-acquisition lifecycle platform, but the checked-in implementation is chiefly a static frontend demo: sampled JavaScript supports navigation, a progress chart, a proposal stepper, and interactive parcel-map layers. The README describes backend workflow/RBAC and spatial-database capabilities, but those directories contain only placeholders; those documented subsystems are shown as unverified, without inferred connections.

Main entry points: [`frontend/js/app.js`](https://github.com/tushar6457-git/sih-2026-land-acquisition-system/blob/main/frontend/js/app.js) (Interface logic), [`frontend/server.js`](https://github.com/tushar6457-git/sih-2026-land-acquisition-system/blob/main/frontend/server.js) (Static file server), [`frontend/index.html`](https://github.com/tushar6457-git/sih-2026-land-acquisition-system/blob/main/frontend/index.html) (Web interface)
