/*
 * Roadmap page (docs/roadmap.md) -- the home page's ruled grid.
 *
 * Loaded only by the unversioned build (mkdocs-unversioned.yml). The page is a
 * `.pgrr-home` sheet (home.css): section bands, the two column lines and the
 * full-width rules come from there. This file only supplies the cells: the
 * title block, the stats, the initiatives and the items are cells cut by
 * hairlines, with no floating rounded cards. The dense text of each item lives
 * in a native <details>, so the page works with no JavaScript; roadmap.js only
 * adds the filter bar, "show more" and "expand all".
