   EXPLICITAI PLATFORM — Design System v3
   Inspired by: Palantir Gotham · IBM Carbon · Bloomberg Terminal
   
   Philosophy:
   · Near-black base, zero decorative gradients
   · ONE primary accent (steel blue), used sparingly
   · Status colors only for data: green=ok, amber=warn, red=alert
   · Greyscale does 90% of the work
   · Monospace for all data, Inter for prose
