The application aims to provide a seamless and luxurious user experience, blending convenience with high-quality craftsmanship.

2. System Overview

The "cosmic-quickcraft" application is designed to cater to two primary user needs: instant delivery of everyday items and a bespoke Aari embroidery customization service. The application will feature a dual-purpose homepage, an interactive customization wizard for Aari work, a smart cart and checkout system, and a dual-track order status screen. The UI will be responsive and visually premium, utilizing Tailwind CSS for styling and smooth state transitions.

• As a User, I should be able to view categories for Grocery, General Store, and Toys with an "Add to Cart" option.
• As a User, I should be able to explore high-quality visual cards for traditional embroidery categories.
• As a User, I should be able to customize Aari work through a multi-step wizard.
• As a User, I should be able to select material, color, design, and work intensity for Aari customization.

6. Signature Design Concept

The homepage of "cosmic-quickcraft" will feature an interactive galaxy map where each star represents a feature or section of the application. Users can click on a star to open a task card, drag to rotate the cluster, and hover to highlight connections. This concept will be brought to life using @react-three/fiber and @react-three/drei for 3D interactions, creating an immersive and engaging first impression. The galaxy map will dynamically shift colors based on the user's interaction, providing a unique and memorable experience.

7. Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model, creating a layered depth effect via scroll. Decorative layers will translate at different speeds, while real content remains in the normal flow. This approach is ideal for storytelling and visually rich first impressions. Internal pages, such as dashboards and settings, will adopt a "static" model to prioritize layout clarity and reading speed.
