System Requirements Document (SRD)

Project Name: brave-webapp

1. Introduction

The brave-webapp, envisioned as CityZen, is a dynamic web application designed to revolutionize city exploration for users in India and beyond. By blending curated insights into events, food, nightlife, and hidden gems with modern features like chatbars, travel cost reimbursements, and personalized city experiences, CityZen aims to become the go-to platform for urban adventurers.

The homepage will feature a black-and-white interface with animated neon lights, including blue neon accents running across key elements.

Details:

• Logo Animation: The logo will glow and pulse with blue neon light, creating a futuristic vibe.
• Sidebar Transition: When the sidebar opens or closes, blue neon lights will trace the edges, giving the impression of a digital circuit board.
• Button Hover Effects: Buttons will emit a subtle blue neon glow when hovered over, with smooth transitions.
• Loading Interface: The directing page will feature a dynamic animation of blue neon lights forming a city skyline, symbolizing exploration.
• Interactive Elements: Pulses will have animated blue neon outlines that flicker slightly, mimicking city lights.

This design will captivate users, making the app feel modern, energetic, and immersive.

7. Non-Functional Requirements

• The system should support dynamic updates for city pulses based on user location.
