   GRITAI DESIGN SYSTEM — "Engineered / Industrial"
   Dark · grit-orange · Archivo + IBM Plex · blueprint grid + grain.
   Canonical source of truth for every GritAI app (30-in-15 #1-30) + the hub.
   Rob-approved 2026-09-05 (#9 pilot: design-critic 5.71 -> 7.57).

   HOW TO USE: embed this <style> verbatim in an app's page, add the Google Fonts
   <link> below, then build the body from the component classes here. Keep the
   header (monogram + app name + tags), grit-orange as the ONLY accent, dark bg.
