bitrix24/bitrix24-dev-hub ? reverse-engineered prompt

Build me a clean landing page for the Bitrix24 developer hub that helps people quickly find the official tools they need.

I want the page to feel like a central directory for Bitrix24 developers, with a strong header, a short intro, and clear sections for SDKs and libraries, UI tools, usage examples, application templates, and documentation. Each item should be shown as a simple card or tile with a name, a short plain English description, and a link out to the official GitHub repo or docs.

Make it responsive, easy to scan, and polished enough to serve as a real homepage. It should work well for someone who is just getting started and also for someone looking for the right tool fast. Use the Bitrix24 branding style if you can, and include the images from the repo in a nice way. If you need to check current docs or best practices online, go ahead and look them up.
