aminkheddache-dotcom/Pterocos — reverse-engineered prompt

Build me a simple online coding playground called Pterocos where people can write HTML, CSS, and JavaScript in the browser and quickly test what they are making. I want it to feel like a lightweight developer tool, with a clean landing page, a main editor area, a preview of the result, and a console for checking output or errors.

Please also add basic pages for projects, community builds, and an AI chat helper, even if they start simple. The project page should feel like a place where users can save or open their experiments later. Community builds should show shared examples or demos. The AI chat page can be a simple assistant interface for asking coding questions.

Use PHP for the main pages since this repo is already set up that way, and keep it easy to run on a normal web host. Make the design modern, responsive, and beginner friendly. Look up current docs online if you need to.
