 - `py.typed` marker for PEP 561 type information.
 - `.drone.yml` CI with a quality-gate step (black, ruff, mypy, pytest).
 - MIT `LICENSE`.
+- `build --refresh` flag to rebaseline an existing `docs/mkdocs.{kind}.yml`
+  from the packaged templates.
 
 ### Changed
 - Standardized `pyproject.toml` (canonical packaging, lint tool config, extras).
 - Pinned the `mcp` extra to `mcp>=1.0.0,<2.0.0` to restore compatibility with
   the current MCP server API used by doc-forge.
+- Per-kind MkDocs configs (`docs/mkdocs.{lib,api,wiki}.yml`) are now generated
+  only when absent; an existing config is used verbatim (the file wins).
+  Pass `--refresh` to regenerate it from the templates.
+- The wiki template now uses the mongo-ops look: horizontal `navigation.tabs`
+  header, blue grey/teal palette, Roboto font, and additional material
+  feature flags. The lib and api templates are unchanged.
 
 ### Fixed
 - Stub fixes for typed API surfaces.
