/*
  Design tokens for the Digital Freight site.
  Single source of truth for colour, type, spacing, radius and shadow values.
  Component and section stylesheets should reference these variables rather
  than hard-coding values, so the design stays consistent as new pages are added.

  Breakpoints (referenced in @media queries throughout — CSS custom properties
  can't be used inside media query conditions, so these are documented here
  and the literal values are repeated where needed):
