sharma11ji/PromptVault ? reverse-engineered prompt

Build me a simple website called PromptVault where people can save, browse, and share useful prompts.

I want a clean landing page, a community page where users can see prompts from other people, and a profile page where someone can view their own saved prompts and basic account info. Make it feel modern and easy to use, with clear cards, simple navigation, and a polished layout that works well on desktop and mobile.

The main goal is to make prompts easy to discover and organize, so include things like prompt titles, short descriptions, tags, and a way to mark favorites or save items for later. Keep the design friendly and lightweight, and if you need anything unclear, look up current docs online and make sensible choices.
