/* The roadmap page (/roadmap.html): a timeline, not a docs article.
   Built on the site's tokens only, so both themes come from site.css's two
   dark blocks (D-574) and nothing here needs a dark copy. The rail runs
   unbroken from the first shipped item to the last planned one: every row
   draws its own segment, so the rows carry padding and never margin. */
