/* ==========================================================================
   DIV SYSTEMS - Case study body
   The case study content is carried over verbatim from divsystems.in, where
   each project page is one custom HTML block. Two component families exist:
     .dsx-*   long-form studies (8 pages)
     .cs-*    shorter studies (LIMS, Port, GroceryGuys); original class names
              were generic (.wrap, .card, .grid) so they are prefixed on import.
   Both are restyled here to the light brand theme. No dark surfaces.
