How else it gets framed

The same term carries different emphasis depending on the surface it’s used on. Both readings are correct.

A markdown file at /llms.txt containing a curated map of a site for AI consumption: an H1 with the site name, a one-paragraph summary in a blockquote, then H2 sections of annotated links to the pages that matter most. Voluntary convention — no assistant is obligated to fetch or honor it.
