/*
 * Blog / editorial design system
 * ---------------------------------------------------------------------------
 * Deliberately distinct from premium.css, which dresses the service and service
 * area pages. Those are marketing pages: dark gradient hero, photo card grid,
 * heavy sans headlines. The blog is for reading, so it uses a light paper
 * ground, a serif headline face, a single narrow measure and list-style indexes
 * instead of card grids. Namespaced .bl-* so the two never collide.
