llms.txt llms.txt robots.txt, but for LLM context.

llms.txt is a proposed standard (llmstxt.org, 2024) for a site to expose a concise Markdown overview of itself at /llms.txt — what the site is, what it covers, and which pages matter most. A deeper /llms-full.txt variant carries the full content corpus. It's the canonical surface for LLMO.
