/* ==========================================================================
   Single post (/blog/{slug}/). Built on the shared page kit (page.css: .pg-wrap,
   .pg-section, .pg-h2, .pg-close…). This file adds:
   .blog-post__*  header: crumbs, category chip, H1, meta row, edge-to-edge cover
   .blog-post__wide  the ~1160px container author-box/related use (was capped by
                      the site's 1440 .pg-wrap, leaving dead space — review item 1)
   .blog-post__grid  2-col from 1024: .blog-prose (720px) | .blog-toc (280px, sticky)
   .blog-toc-mobile   collapsed <details> right after the cover — never after the
                       article (review item 2); the sidebar below is desktop-only
   .blog-inline-cta   one contextual service prompt spliced ~25-35% into the article
                       (App\Support\Blog::spliceBeforeHeading, before the 3rd h2)
   .blog-prose    typographic rules for the rendered Markdown body + numbered h2
                   eyebrows (CSS counters) + a flatter "evidence" image treatment
   .blog-toc*     sticky sidebar TOC (14px, active-state) + service CTA card
   .blog-author*  wide author band: monogram, role, "4 businesses" stat, links
   .blog-cover*   honest editorial cover (duplicated — see blog.css's header note)
   .blog-grid/.blog-card  related posts (duplicated from blog.css — see its header note)
