– SQL schema and seed data scripts.
– Comprehensive documentation covering setup, feature usage, and customization.
**Steps:**
1. Set up project directory structure and initialize Git version control.
2. Design and implement the MySQL database schema with sample seed data.
3. Build secure user authentication system with role-based access control.
4. Develop backend API endpoints for all user-facing and admin functionalities.
5. Create frontend layouts and components with responsive design and neon cyberpunk styling.
6. Implement animations using GSAP or CSS keyframes.
7. Integrate homepage, dashboards, forum, listings, reviews, ads, subscription system, and dynamic ad rotation.
8. Perform thorough testing including cross-browser compatibility, responsiveness, SEO, accessibility, and security.
9. Document the system with setup guides, feature details, and customization instructions.
**Output Format:**
– Provide a well-organized, modular codebase with inline comments explaining key parts.
– Include sample implementations for major components such as:
– Homepage hero section
– User registration/login
– Admin dashboard
– Forum threads
– Deliver SQL schema and seed data as separate .sql files.
– Provide detailed documentation as markdown files within the repository.
**Notes:**
– Ensure all components are reusable and maintainable.
– Prioritize security best practices: input validation, prepared statements, password hashing, and OAuth implementation.
– Handle user errors gracefully with informative feedback.
– Apply SEO best practices such as semantic HTML5 elements, meta tags, and optimized loading.
