Omnikon-Org/Website ? reverse-engineered prompt

Build me the official website for Omnikon, an open source tech community. I want a modern, fast, and responsive site that feels polished on desktop and mobile, and acts like the main hub for the organization.

It should showcase Omnikon projects, contributors, community blogs, announcements, and general org updates. I also want live GitHub related stats and dynamic content pulled in where it makes sense, plus a simple authentication flow for Google and GitHub if that fits the site. Make it look clean and community focused, with good SEO, smooth performance, and a strong landing page that explains what Omnikon is all about.

Use the existing content and assets if they help, and keep the site easy to extend later. If you need to look up current docs online for anything, go ahead.
