/* ===================================================================
   Case Study detail page redesign (single-case_study.php)
   Reuses the site's existing --wblog-* design tokens (defined in
   style.css) for color/shadow so this stays visually consistent with
   the Blog redesign; only fills in the few shades that redesign
   didn't need (ink800/900, tint background, soft accent border).
   =================================================================== */
/* Defined on :root (not scoped to .csd) — the "Related case studies" grid and the
   comments block render as siblings after </article class="csd"> closes, so a
   .csd-scoped custom property would be out of scope there and silently fail. This
   file is only enqueued on singular case_study pages, so page-wide scope is safe. */
