/* Kudenix Listado del Blog — Scoped under .kudenix-blog-listing
   Origen: propuesta/pages/blog.html, sección "Nuestros Blogs".

   Geometría revertible: el default del grid (3 columnas, gap 32px) vive aquí
   bajo la clase raíz con doble selector (skill §3.bis); el control
   posts_per_row del widget usa selectors_dictionary y solo emite override
   cuando el editor elige 1, 2 o 4 columnas explícitamente.

   Tokens redeclarados con prefijo `kbl-*` (skill §4.c) para no contaminar :root.

   Webfonts: Google Fonts equivalentes a Helvetica Neue LT Std.
   Roboto Condensed 700 ≈ Helv Neue LT Std 67 Medium Condensed (heading).
   Roboto 500 ≈ Helv Neue LT Std 65 Medium (títulos de cards).
   Roboto 400 ≈ Helv Neue LT Std 55 Roman (excerpts).

   Layout: masonry con CSS Columns (column-count + break-inside: avoid).

   id=10 blog-listing-enhancements:
   - F4: --kbl-aspect-ratio token (default 4/3) controlado desde el widget
     vía selectores_dictionary sobre .kudenix-blog-listing. El override del
     control Elementor emite `--kbl-aspect-ratio: N / M` directamente en el
     wrapper, y la regla .kudenix-blog-listing__item-image / __placeholder
     usa `aspect-ratio: var(--kbl-aspect-ratio)`. */
