   Weathered zinc + copper. Archivo (display) / Source Serif 4 (body).

   Deliberately not the red-white-blue of every competitor in this market.
   A serif body face is the fastest way to look unlike the other five
   results on the page.

   Contrast: --copper (#B0561F) on white = 5.0:1. Body ink on bone = 14.8:1.
   Every interactive target is >=44px. Motion respects prefers-reduced-motion.

/* =========================================================================
   26. SPEC-SHEET LAYER
   The differentiator. Three ideas:
     1. A standing-seam motif — hairline verticals at panel intervals — so the
        page refers to the product instead of being palette-swapped boilerplate.
     2. Serif for long-form headings, Archivo kept for UI. The serif was
        previously used in 2 rules against Archivo's 47, so the one
        distinguishing type choice was invisible above the fold.
     3. The verified facts (50 psf, 3/8", 24", $12-16) set as data, not as bold
        text buried in a paragraph. The research advantage made visible.
