"""AtoCore Wiki — navigable HTML pages from structured data.

A lightweight wiki served directly from the AtoCore API. Every page is
generated on-demand from the database so it's always current. Source of
truth is the database — the wiki is a derived view.

Routes:
  /wiki                     Homepage with project list + search
  /wiki/projects/{name}     Full project overview
  /wiki/entities/{id}       Entity detail with relationships
  /wiki/search?q=...        Search entities, memories, state
