/**
 * author.css — author archive deltas (author.php), ported from author.html.
 *
 * Enqueued on is_author() AFTER css/blog.css, which supplies the :root palette,
 * .btn family, shared .blog-card grid, pagination, and the light-background
 * .breadcrumb. This file adds only the blue author hero, the white breadcrumb
 * override for that hero, the profile/stats/social block, and the expertise
 * strip. Theme chrome comes from header.css / footer.css.
