/* =================================================================
   Mali Richlen Advisory — Case Study Detail Pages
   ----------------------------------------------------------------
   Page-specific CSS for the long-form case study detail pages
   (Manufacturing, Retail, and any future studies).

   The case study uses an alternating paper/cream section rhythm,
   a numbered block as the section anchor, plus a few specialized
   list patterns: cs-risk-grid (2-up risk cards), cs-priorities-cols
   (numbered priorities list), and the cs-pattern-line italic
   bridge between blocks.

   The breadcrumb at the top of each detail page uses the unified
   `.breadcrumb-row` partial from site.css — NOT the legacy
   `.cs-crumbs` class (intentionally omitted here).

   Loads AFTER tokens.css → globals.css → site.css.
