/**
 * Blog post – page-scoped only.
 *
 * The reading experience is the design: the kit's 68ch `.prose` measure, real
 * air before every section head, and a sidebar that supports the article
 * instead of selling against it.
 *
 * THIS PAGE CARRIES NO RED. The kit paints the accordion's "+" marker with
 * `--red`, which is correct everywhere except here, so §4 below repaints it
 * blue. That override is exactly what a per-template stylesheet is for.
 * pages.css is not edited. AGENTS.md §2.
 *
 * One token gap, same as blog.css: the 44px tap target has no token, so the
 * share discs, the contents links and the back link take `--btn-min-height`
 * (48px). Larger, so still clear of the accessibility floor. A `--tap-min`
 * token in tokens.css would close it.
 *
 * NOT BUILT: the mock-up's reading-progress hairline. It is decorative, it
 * needs a scroll listener, and this template ships without a JS file of its
 * own, so it is skipped rather than half-done. Nothing below references it.
