 * PAGE: Single Blog Post (single.php)
 * =============================================================================
 * Layout + prose styles for a single `post`. The hero, quick-links and
 * request-demo blocks bring their own stylesheets; this file styles the
 * article body (the_content) and the Related posts row. Tokens only —
 * see variables.css.
 *
 * Sections:
 *   .single-article          → the_content() wrapper (prose)
 *   .single-related          → "Related posts" heading + 4-card grid
