/* Gate-automation landing pages (tools/gate-pages/build.mjs).
   Same storefront look as the store (products.html): grey page, white panels, dark ink, brand-green CTAs,
   4px corners, soft shadows — the layout leading B2B marketplaces use (breadcrumb, gallery + buy box,
   spec table, product-card grids, sticky quote card). The site header comes from css/site-header.css. */
