/**
 * BEYOND — styles du blog uniquement
 * -------------------------------------------------
 * Extrait de style.css pour isoler tout ce qui concerne blog.php /
 * blog-ajax.php (liste, vue article, lecteur YouTube inline). Les
 * variables globales (--blue, --pink, --violet, --text, --text-dim,
 * --hairline, --gradient, --bg, --bg-alt, --ease, --font-body...)
 * restent définies dans :root, dans style.css, et sont réutilisées
 * ici telles quelles — ce fichier ne redéfinit aucune variable, il
 * doit donc être chargé APRÈS style.css.
 *
 * Composants volontairement laissés dans style.css car partagés
 * avec d'autres pages : .page-head (actualités / portfolio / blog),
 * .filter-bar / .filter-btn (portfolio + blog), .btn-lb (bouton rond
 * fixe de base, dont .blog-scroll-top n'est qu'un habillage).

/* ---------------------------------------------------------------
   Blog — une ligne par article : rail de dates, vignette, texte.
   Un filet en dégradé (repris du soulignement des liens) marque la
   ligne survolée ; la vignette reprend la lueur néon déjà utilisée
   sur le portfolio et les boutons, sans réinventer un style de carte.
