   SMARTS — DRAP Registration · GLOBAL STYLES (v4)
   One file defines the whole design system: tokens, type, layout, buttons,
   header, footer, shared components and motion rules. Page files
   (home.css / pages.css) only add page-specific layout on top of this.
   Signature motif: the slanted "speed lines" from the SMARTS logo.
