The homepage is at https://rushabhshah.dev/index.md. The older `index.html.md` spelling still resolves for every page. Each HTML page also links to its own twin with `<link rel="alternate" type="text/markdown">`. https://rushabhshah.dev/llms-full.txt is every one of those mirrors concatenated into a single file.
