Styled App Bar - Copy this React, Mui Component to your project

I want to design a website for selling game accounts with a diverse, modern, and aesthetically pleasing interface, while keeping it minimalist. The website should include the following features: Overall Interface: A minimalist, clean, and refined style with a light theme and subtle color accents. Homepage: Display various game categories (e.g., RPGs, shooters, MOBAs, etc.) along with best selling accounts and special offers. The content of the website should be consolidated onto a single page where users can easily browse without having to search too much. Product Detail Page: The game account detail page should provide all necessary information (such as level, items, etc.), with clear 'Buy' buttons and an 'Add to Cart' option. Prices should be displayed in Vietnamese Đồng (VNĐ). Cart and Checkout: A clean, user friendly cart interface that is minimal but still intuitive. The checkout process should be smooth, with various payment methods available. Payment Integration: Needs to have modern, secure, and user friendly online payment integration. Admin Section: A simple, easy to use admin interface for managing orders, accounts, and customers, with visual reports of revenue and sales. Design Style: Use Fluent Design or Material Design with smooth effects, focusing on aesthetics and user experience without being too overwhelming. Sidebar: The sidebar should only contain essential user actions, such as a top up (deposit) page, purchase history, and user balance information. Unified Content: Ensure that the entire website’s main content is easily accessible on one page without requiring the user to search too much, keeping navigation simple and intuitive. Currency: The website should display all prices and balances in VNĐ (Vietnamese Dong).
