/* ============================================================
   CASE STUDY — long-form paper surface + data visualization.
   Loaded AFTER colors_and_type.css and pages.css.
   Light (parchment) palette only; the dark site chrome stays.

   Structure:
     .cs-shell            dark page gutter
     .cs-paper            the sheet
       .cs-col            760px prose measure (all text)
       .fig               breaks the measure, full sheet width
   Semantic data palette is defined once in :root below — never
   encode meaning by color alone, every state also has a label.
