/* ============================================================================
   Preston-Check Admin Portal — visual system

   Reuses the brand tokens from the public landing page (web/landing/styles.css).
   Adds layout primitives unique to the operator surface: persistent left rail,
   top bar, multi-section detail panes, dense data tables, KPI tiles, and small
   inline SVG charts.

   Density target: 1280×800 minimum, 1440×900 sweet spot. The portal is an
   operator's daily driver — denser than marketing, breathing room compared to
   a Bloomberg terminal.
