Building the docs target now generates the reference and leaves finished documents in the build tree's docs directory: pdf/ holds the compiled PDF, html/ holds the browsable reference when that format is enabled. Doxygen and LaTeX work under docs/tmp/, which clean removes along with the rest of the tree. The reference has a front page and a structure. The markdown documents in docs/ are part of the input, OVERVIEW.md becomes the landing page, and the rest follow as chapters ahead of the namespace, class, and file reference. The module contract, previously a plain comment block invisible to Doxygen, is a page in its own right. Struct and enum members throughout the headers carry documentation, on their own lines above what they describe.
