   Taabi Tickets — design system.

   Same skeleton as prom.taabi.co (token names, card/control/chip rhythm, icons),
   recoloured: the Taabi orange ramp becomes a light-green radiant gradient that
   is easy to sit in front of all day. Text always sits on a checked pair
   (--color-primary/--color-primary-ink, --color-ok/--color-ok-soft, …);
   decorative green (rings, gradients, the mark) uses --color-brand-*.
