Design a clean and modern user interface for an e-commerce platform focused on building materials, home decor products, and related services. The interface features a three-level product categorization system. Home Page (First-Level Categories): Display 6 main 'Product Categories' such as 'Building Materials,' 'Garden Supplies,' 'Cabinets & Furniture,' 'Lighting,' etc. Each category should be represented by a simple, elegant icon or image. Additionally, display 3 main 'Service Categories,' such as 'Delivery Services,' 'Installation Services,' 'Repair Services,' each with a clear, minimalist icon design. All categories should use a minimalist card layout with clear, prominent titles. When a category is selected, it navigates to the second-level category page showing subcategories. Second-Level Categories: Upon selecting a subcategory, the interface should display a grid of smaller tiles or list items representing the third-level categories. Each category should include a simple image or icon and a brief description. For example, under 'Flooring Materials,' display third-level categories like 'Hardwood,' 'Tiles,' 'Carpets,' etc. Third-Level Categories: This page should present a scrollable list or grid of products, including small thumbnails, product names, and prices. The design should be clean and functional, allowing users to easily filter and sort products. Overall Design Aesthetics: Use a limited palette of 2-3 colors, with a focus on neutral tones and one accent color. The 'NestWorks' platform name should be in a creative font, while product descriptions should be in a clear, readable font. The design should be intuitive, ensuring seamless navigation between different category levels. Icons and buttons should be simple, flat, and easily recognizable to enhance the overall user experience.
