/* blog.css — styles du blog BigFive Coworking.
 *
 * STUB PROVISOIRE (30/07/2026). En attente de la référence blog.css de Rhiino
 * (demandée via le canal handoff : handoff-rhiino-blog-css.md) pour caler la
 * structure, puis réadaptation complète à la charte BigFive (navy #121D2F /
 * corail #EB4C51, Playfair Display + Inter). Ce fichier évite un 404 de la
 * feuille de style et pose des règles minimales lisibles en attendant.
 *
 * Classes ciblées : .blog-index-hero .blog-filters .blog-filter .blog-grid
 * .blog-card .blog-article-hero .blog-theme-badge .blog-article-wrap .blog-toc
 * .blog-share .blog-cta-inline .blog-faq .blog-author-box .blog-related
 * .blog-cta-final .reading-progress .blog-cover-fallback
