/* File2Forge — design system
   Precision-industrial aesthetic. Charcoal + white + laser-orange accent.
   Orange (#E97F2A range) reads as heat / laser / industrial — it lives on
   eyebrows, primary CTAs, hover borders, and as a glow on the dark marking
   spotlight. Modeled on SendCutSend's clean upload-first UX, with a sharper
