f/prompts.chat ? reverse-engineered prompt

I want to build a private prompt library for my company. The idea is to have a central website where we can collect, share, and organize the best prompts our team uses for AI tools like ChatGPT and Claude. It should function like a community hub, but it needs to be private and self-hosted for our organization.

Users should be able to browse the entire collection, search for prompts by keyword, and submit their own successful ones for others to use. A crucial part is being able to customize it with our company's logo and color scheme. I'll also need a straightforward way to set up user authentication so only our employees can log in, preferably using their existing Google or Microsoft work accounts.

Please build this using a modern stack like Next.js and TypeScript. It should be easy to deploy, so including Docker support would be great.
