/* ============================================================
   Ítaca Tower · Blog (index + article), ES and EN
   Porta Nova's blog layout (assets/blog.css) restyled in Ítaca's brand:
   Raleway, steel blue #41768F, navy #11313D, aqua #BEE6EC.
   Reuses tokens, header, footer, buttons, .ph and .g-ref from
   /styles.css + /itaca.css. Linked AFTER both. Lives in /blog/ so
   the blog never touches the landing's files.
