/* Horizon Technologies — product page ("hz_oferta" single) stylesheet.
   Loaded ONLY on single-hz_oferta.php (see functions.php), on top of
   main.css — reuses main.css's tokens, .wrap/.icon/.eyebrow/.display/
   .btn*/.reveal/.header/.feature-grid/.feature-card/.process-rail/.step/
   .placeholder-photo/.cta/.footer as-is rather than redefining them, so a
   product page always stays visually identical to the rest of the site
   wherever it reuses a component. Only the genuinely new, product-page-
   specific pieces (breadcrumb, hero, sticky sub-nav, layer diagram,
   variant cards, application tiles, spec sheet) live here. */
