Build an e-commerce product listing with filters

• Shows a grid of products from a local dataset (at least 40, with category, brand, price, rating, in-stock flag)
• Faceted filters: checkbox groups for category and brand, a price range, a minimum rating, and an in-stock toggle; groups combine with AND, options within a group with OR
• Each facet option shows a count of matching products given the other active filters
• Sort by relevance, price low to high, price high to low, and rating; pagination (or Load more) of 12 per page
• All filters, sort and page are stored in the URL query string; reloading or sharing the link restores the same view and Back works
• Active filters appear as removable chips with a Clear all action
• An empty state when nothing matches, suggesting which filter to remove
• Filters collapse into a drawer on narrow screens

Only after every requirement works.

• Debounce the price slider and text search
• Highlight facet options that would yield zero results (disabled)
• Skeleton loading while a mocked API responds
