Replaced the primary nav (About · Substrate · AI & Provenance · Publication log) with five plain-language content categories, plus Encyclopedia and About: Recovery & Becoming, Meaning & Narrative, Literature & Imagination, Connection & Peer Support, and Substrate & AI. AI & Provenance and the Publication log moved to a secondary utility line on each page rather than the primary nav.
The five categories are informed by an internal editorial ontology, kept separate at Explore the Living System, not exposed as nav vocabulary. Two of the five (Substrate, Connection & Peer Support) currently list two published items each; several posts that would strengthen them are drafted but not yet through human review. Left visible rather than hidden, consistent with this site's practice of showing unfinishedness rather than smoothing over it.
