/* ============================================================
   SAYOANG — product detail shell (공통 셸 + 제품 스킨).
   Shared LNB · price row · hero CTA pair · #buy block · bottom buy bar for
   every native product detail. Markup: inc/product-shell.php (rendered by
   single.php + partials). Loaded on product singles from inc/enqueue.php,
   before the per-product stylesheet.

   Skin = four custom properties set inline on .sy-pd by single.php:
   --p-accent (active underline, highlights) · --p-accent-text (accent as text,
   ≥4.5:1 on white) · --p-soft (tint) · --p-cta / --p-on-cta (button fill/text,
   ≥4.5:1) · --p-display (headline face). UI text is always Pretendard.
