   nebty investigations — public dataset browser
   Tokens are lifted verbatim from the nebty design system (colors_and_type.css).
   House rules being followed here, from the system README:
     - Montserrat for headings, Lato for text, both from Google Fonts
     - gray-50 canvas, white cards, 1px borders (borders AND shadow, so it reads
       as a dashboard rather than as marketing)
     - radius 8px, shadow-sm/md only, no glow and no coloured shadows
     - no glassmorphism, no backdrop blur, no left-accent-border cards
     - motion 150-300ms ease-out; hover shifts the brand hex one step darker,
       never a scale; no continuous animation except a loading spinner
   ========================================================================== */

   off-screen with no scrollbar, no fade and no hint they existed.
   Below 768px each row becomes a card instead. Nothing is dropped; the columns are
