/* TBredIQ — Editorial / Data-Terminal design system

   A single stylesheet that every page links once. No glass-blur, no
   gradients, no AI-default tells. Broadsheet typography, hairline

   Color:  warm-dark ink #0e0d10 + paper-inverted off-white + signal-green
   Motion: restrained — one staggered page-load reveal; respects reduced-motion */
