/* Vercel-grade light design system — authored for Asquad B2B export templates.
   Design DNA: vercel.com / Geist design system (DESIGN.md): pure white #ffffff canvas,
   near-black #171717 text, shadow-as-border (0px 0px 0px 1px) instead of CSS borders,
   Geist-style aggressive negative letter-spacing, three-weight system (400/500/600),
   achromatic palette with functional accent colors only (Develop Blue / Preview Pink /
   Ship Red used solely to mark pipeline stages). NOT a copy of Vercel's content —
   colour/type/layout language only. Geist is loaded from Google Fonts. */
