## Overview

Enhanced Parking System combines a Flask parking dashboard and account flow with camera-based vehicle/spot detection, plate-text recognition, and live parking-state updates. The main runtime path captures video, detects occupancy, associates OCR text, updates in-memory spot state, and serves status and video to browser views. Registration also persists users in SQLite. The README is empty; the map follows the sampled runtime code and tree, and omits uncertain wiring such as the separate your_project prototype.
