Renders the cohere docs site: authored markdown in docs_src/ becomes static HTML in docs/, alongside pages derived from the compiled tasks and the repo's own coherence artifacts.

The site is built on the tool's own split — derived where possible (command reference from task moduledocs, the self page from the live map), authored where necessary (the narrative pages). The renderer covers only the constrained markdown subset the authored pages use; we author the input, so completeness is a non-goal — the same judgment as hand-parsed frontmatter over a YAML dependency.

Rendering is deterministic: same sources in, same bytes out. Nothing here reads a clock, the network, or git state, so a CI rebuild plus git diff --exit-code docs/ is a complete freshness gate.
