/* ==========================================================================
   Export Site - Design System
   Tokens extracted from Sasonix Webflow template (css/sasonix.app.shared.*.min.css)
   Palette actually shipped by the template: orange #ff6c02 + warm cream neutrals,
   NOT the blue/purple the README claims. Orange + cream suits manufacturing
   exporters better than it suits an AI SaaS brand, so it is kept as-is.

   Typography scale (2026-10-15) realigned to the template's own tokens:
   h1 80 / hero 60 / h2 48 / h3 40 / h4 24, body 18 @ 300 weight, headings 500,
   letter-spacing -2px / -1px, line-height 110% / 170%. Small text (14-16px) is
   bumped back to 400 because 300 renders too faint at that size.
