/* ───────────────────────────────────────────────────────────────────────────
   Understanding Diamonds page — header + summary cards + four detail sections.
   Matches the clean page-header layout used by the FAQ and Testimonials pages
   (no full-bleed hero). Reuses the story / values patterns from the About page
   (these live in page-scoped CSS, so the needed rules are included here) plus
   styled scale and shape lists specific to this page.
