/* ==========================================================================
   Lutz Ferrando · Listado de blog ("Consejos y novedades") — editorial premium
   Se carga SOLO en template == 'blog' (ver layouts/layout.tpl), después de
   lf-fonts.css + lf-shell.css + lf-global.css + lf-products.css, así que
   puede usar directamente los tokens y clases de marca ya definidos ahí
   (--verde-txt, --bronce, .kicker, .btn/.btn--primario, .aurora, .grano,
   .sello, [data-reveal], etc.) sin volver a declararlos.

   SCOPE: ningún reset global (`* {}`) — todo queda anidado bajo los
   contenedores propios de esta página (.lf-blog-*) para no tocar Morelia
   en otras vistas. Todo lo nuevo va prefijado "lf-blog-".

   GOTCHA heredado (ver lf-global.css sección BLOG / lf-shell.css sección 7):
   el contenedor de la imagen destacada (`image_container`) recibe de
   Tienda Nube un padding-bottom inline calculado según el aspect ratio real
   de cada foto, y la <img> ya trae position:absolute + object-fit vía las
   clases nativas "img-absolute img-absolute-centered" (que se preservan
   intactas en blog.tpl, solo se les suma la clase propia). Por eso acá NO
   se fuerza aspect-ratio en .lf-blog-card__fig: se respeta el recorte real
   de cada nota, más editorial que forzar un box parejo.
