   Design system: vehicle cockpit / HUD / engineering drawing.
   Voice: fast, technical, precise, energetic. Cool graphite
   bands, electric blue + energy green, monospace data readouts,
   geometric sans display, sharp radii, crisp rules. Deliberately
   NOT a warm editorial look (see HomeOfficeErgo): no serif, no
   paper tints, no soft rounded cards.
