I need my existing e-commerce store re-skinned with a vibrant, colorful theme that instantly feels lively yet stays clean enough to guide shoppers toward checkout. The redesign must cover the full customer journey—home, category, product, cart, and checkout—while staying fully responsive on mobile, tablet, and desktop. The new look should load fast, follow modern UI/UX best practices, and keep branding elements easy to update in the future. Please build the layout with accessible, well-commented HTML/CSS/JS (or the native templating language of the platform you prefer) so I can drop it straight into my current shop without breaking functionality. Essential feature integration: • User reviews and ratings • Product filtering and sorting • Wish list functionality Final hand-off includes the compiled theme files ready to install, layered design sources (Figma, Adobe XD, or Sketch), and brief documentation on how to swap colors, fonts, and graphics. A quick screen-share walkthrough once everything is in place will close the project.
