dod-advana/GAMECHANGER ? reverse-engineered prompt

Build me a polished public landing page for GAMECHANGER that explains what the project is in plain language and makes it easy to understand the mission.

It should feel like an official government open source project, with a strong hero section, the logo, a short summary of how it helps the DoD navigate requirements and policy documents, and clear sections for Vision, Mission, and the related repositories. Include simple cards or links for the main companion projects like data, machine learning, web app, crawlers, and the Neo4j plugin, plus a short note about licensing and contributing.

Keep the design clean, trustworthy, and accessible, with responsive layout and good typography. Use the existing branding assets where possible, and make sure the page works well as a README style homepage or simple website. If you need to, look up current docs online for any best practices, but keep the build focused on presenting the project clearly rather than adding extra features.
