/* ============================================================
   OliverDeck — COMPONENT · SECTION PATTERNS
   Page-level composed blocks: hero (4 variants), section header,
   founder column (4 variants), big stats, material comparison,
   calculator shell, glossary, article/editorial, quiz, checkout.
   These build on the primitives + cards above.

   NOTE: the hero background image was hardcoded to an external
   oliverdeck.ru URL in the original CSS. It is now a token:
   --od-hero-image. Set it per-page (inline style or a wrapper);
   default is a self-contained warm gradient (no external dep).
