   Manufacturing Equipment sample pages

   A landing-page layout: a product-style hero (photo viewer with a thumbnail
   rail beside the plant summary), then full-width sections on alternating
   backgrounds with pill eyebrows, rounded cards and soft shadows. Warm
   amber/orange to match the manufacturing gallery. No inline styles anywhere
   in the template (CSP ratchet).
