godotengine/godot-docs ? reverse-engineered prompt

Build me a clean documentation site for the Godot Engine, using the existing content structure and making it easy to browse guides, class reference pages, community info, and getting started material.

I want the site to feel like the official Godot docs, with a polished light and dark theme, good navigation, search, and responsive layout for desktop and mobile. Please make sure the pages can be built locally and exported as a static HTML version for the web, and also as an ePub for offline reading.

If anything needs current setup details, check the latest docs online before changing things. Keep the writing and page structure easy to maintain, and make sure the result works well for both people learning the engine and people looking up reference docs quickly.
