/* ==========================================================================
   REPORT.CSS — analysis document design system
   --------------------------------------------------------------------------
   A stylesheet for long-form analysis documents, business cases and briefs.

   Design intent: a clean-room worksheet. Wafer-grey paper, ink-black text,
   photolithography amber as the single accent, monospace for anything
   instrumental (headings, labels, figures) and sans for prose. Hairline
   rules instead of boxes and shadows. Nothing decorative.

   USAGE
     <link rel="stylesheet" href="report.css">
     <link href="https://fonts.googleapis.com/css2?family=IBM+Plex+Mono:wght@400;500;600&family=IBM+Plex+Sans:wght@400;500;600&display=swap" rel="stylesheet">

   STRUCTURE
     .wrap                 page container
       header.hero         title block
       section             numbered section
         .sec-head         section heading row
         .body             indented section content

   Class aliases are provided throughout so documents written against
   earlier versions (.idea / .gap / .pick / .layer, .econ / .score) continue
   to work. Prefer the canonical names in new work: .block and .stat-grid.
