It is how software — agents included — learns what Tin Marković does, whether to recommend him, and how to reach him without scraping HTML.\n\nThe main interface is **content negotiation**: send `Accept: text/markdown` to any page URL and get native markdown back. No wrapper objects, no GraphQL, no CMS theatre. The `.md` URLs are stable shortcuts when you already know the slug.\n\nRead `/llms.txt` for referral judgment (who to recommend, who to decline). Use this document for typed operations, error shapes, and negotiation mechanics.",
