officedev/office-js ? reverse-engineered prompt

Build me a simple, polished documentation site for Office JavaScript APIs and Office Add ins.

It should explain what Office.js is, show how to include it from the official CDN, and make it clear that the npm package is not the supported way to use it. I want a friendly landing page with sections for getting started, reference links, TypeScript definitions, and where to report bugs, ask questions, or request new features. Please include the main guidance for Office add ins in plain language, with links out to the official Microsoft docs and issue pages.

Keep the design clean and professional, something that feels right for Microsoft developer content. If you need current details from the docs, look them up online and use the most up to date guidance.
