   PDG BLUE METAL — Stylesheet
   A construction-materials supplier site built around the brand's own
   quarry badge. Signature motif: the "gradation bar" — a graded strip of
   swatches echoing how aggregate is sieved and sold by size (40mm down to
   dust). It marks section breaks and product cards throughout the site.

/* Lucide icons inherit currentColor by default and default to a 2px stroke;
   thinning to 1.75px keeps the same light, premium line weight the original
   sprite icons used. Existing size rules (svg{...}) elsewhere in this file
   continue to apply unchanged since Lucide renders a plain <svg> in place
   of each <i data-lucide> element. */
