/* Blog v2 prototype. Everything is scoped to .ynb (the new <main>), so the site header and footer keep
   the theme's styles. Layout: a dark hero under the transparent site header, then a 220px sticky
   contents column beside a ~68ch article column; the blog home is a lead story + side list, a reading
   path band and a three-column card grid. */
