   PixelNews — flat, modern intelligence-dashboard theme.
   Rule: no gradients, no box/text shadows, anywhere. Flat fills + hairline
   rules + deliberate color blocking only. Primary accent is #dc2626.
   Typography: Space Grotesk (display) + Inter (body) + JetBrains Mono
   (data/metadata) — a contemporary product-UI pairing, not a newspaper face.
