   I Love Wejdan — visual identity
   Clean, light interface: white cards on a very light cool-grey page,
   subtle borders, rounded corners and violet accents for everything
   interactive. All colours come from the tokens below; components
   further down only reference tokens.

   File-type colours (--ft-*) and status colours (--success/--warn/
   --error) are separate systems and never depend on each other.
