HeyPuter/everything ? reverse-engineered prompt

Build me a polished web app that feels like a home base for a whole suite of open source productivity tools.

I want a landing page and app launcher for the project, with clear sections for office, collaboration, creative tools, engineering, productivity, finance, business, developer tools, and games. Show each app as a card with its name, a short plain English description, and a way to open it or view the source. Make it feel modern, friendly, and ambitious, like a real product people would want to explore.

Use the existing project style and assets where they make sense, and make sure it works well on desktop and mobile. The main goal is to help someone quickly understand what’s available and click into the different apps. If you need current details or better UX ideas, look up the latest docs or best practices online and use those.
