 * seo-additions.css
 * Styles for SEO pass additions — April 2026
 *
 * Covers four areas added in Tasks 04-07:
 *   1. Product detail sections (.prodpage > .fullwidth and .sm-why-box)
 *   2. FAQ accordions (.sm-faq)
 *   3. Blog pages (.sm-blog-post, .sm-blog-card, .sm-blog-listing)
 *   4. 404 page (.sm-404-hero, .sm-404-links, .sm-btn-orange)
 *
 * Selectors are scoped to .sm-* prefixes or existing unique class names
 * (.faq-area was replaced with .sm-faq in markup) to prevent bleed-through
 * to existing site pages.
 *
 * Brand reference:
 *   Orange:      #f26520 / linear-gradient(to right, #f26520, #C84A00)
 *   Dark:        #212121 (CTA/footer bg) / #121212 (body text)
 *   Gray bg:     #f4f6f7 / #eee
 *   Font:        "Poppins", sans-serif

   White card treatment for .fullwidth blocks that sit directly
   inside .prodpage but OUTSIDE the .proddesc CSS grid.

   the .proddesc ancestor — these new blocks don't have it.)

   product page) double up .prodpage's 60px top + 80px bottom padding,
   creating a 140px dead zone between sections. Zero the inner gap so
   the two stacks read as one continuous content area.
