OshekharO/Web-Indexer ? reverse-engineered prompt

Build me a clean, fast website called Web Indexer that acts like a one stop directory for finding sites and apps across categories like manga, light novels, movies, anime, learning resources, apps, and optional 18 plus content with a clear consent warning. I want people to be able to search quickly, filter by category, open entries easily, and save favorites in their browser so they can come back to them later. Please include light and dark mode, a responsive layout that works well on mobile, and a simple way to suggest new sites or report broken ones using GitHub issue links or a similar flow. It should feel lightweight, modern, and easy to browse, with good accessibility and basic SEO so it can be shared and discovered easily. If you need to look up current docs or best practices online, go ahead.
