MicrosoftLearning/AZ-104-MicrosoftAzureAdministrator ? reverse-engineered prompt

Build me a clean course website for Azure Administrator training that organizes the lab instructions, demo links, and supporting files in one place. I want a simple homepage that explains what the course is, points people to the hands on labs, and makes it easy to jump to each lab without getting lost. The pages should be easy to update over time since the Azure portal changes often, and the lab content should support instructor led delivery with separate files for the lab exercises. Please make it look polished but straightforward, with clear navigation, readable instructions, and a good layout for GitHub Pages. If you need to, look up the current best way to structure a static docs site like this online. Include support for downloadable lab materials and make the whole thing easy for instructors to maintain and update later.
