FedML-AI/FedML ? reverse-engineered prompt

Build me a simple but polished landing site and docs experience for FEDML that explains what it does in plain English, for training, model serving, and federated learning across cloud, on premise, edge devices, and phones.

I want it to feel like a real product homepage, with a clear hero section, short feature highlights, a few use case sections, and obvious calls to action for documentation, community, and getting started. Please also make sure the project is easy to run locally, and if anything is unclear from the repo, look up the current docs online and match the existing FEDML branding and terminology.

If there are any existing example pages or assets in the repo, reuse them instead of inventing a new style from scratch.
