Private Build

The private docs build includes every page in docs/site. It is the internal operator portal and the default target for new pages because missing visibility front matter is treated as private.

CI Contract

MkDocs build	Builds the full portal from one source tree.
Markdown twins	Emits a .md twin for every included page.
LLM index	Emits /llms.txt at the site root.
