Develop a highly responsive and visually appealing product detail page for an e-commerce store. This project will focus on translating a given UI/UX design into a functional frontend, showcasing product images, detailed descriptions, pricing, quantity selectors, and an 'Add to Cart' button. It will emphasize component reusability, state management for interactive elements like quantity, and robust responsive design for seamless viewing across various screen sizes (mobile, tablet, desktop). The goal is to create a polished, user-friendly interface that demonstrates strong frontend development skills.
