/* ===========================================================
   Case Study v2
   ===========================================================
   Shared styling for template-parts/case-study-layout.php. Written once
   against --csv2-* custom properties (surface / surface-soft / ink-accent /
   hero-bg), which the layout template resolves per instance from a
   green|orange|brown accent flag and emits inline on the .csv2 wrapper —
   see that file for the color resolver. Adding a new accent later is one
   new entry there, not new CSS here.

   Namespaced csv2- (not the legacy .cs-* family used by the other 4
   case-study pages, which stay on their existing hardcoded-per-section
   styling until they're opportunistically migrated) so nothing here can
   collide with or restyle a page that hasn't migrated yet.
   =========================================================== */
