   KOBIL Agent Trust — Developer Portal component layer

   REQUIRES styles.css to be linked BEFORE this file. This is a component
   layer only: it defines no tokens of its own and resolves
   --bg --surface --surface-2 --surface-3 --border --border-light
   --text --text-secondary --text-muted --blue --blue-dim --violet
   --violet-dim --cyan --emerald --amber --amber-dim --radius --sans
   --mono and the @property --angle conic border from styles.css.
   Tokens are deliberately NOT duplicated here, so there is a single
   source of truth and no chance of the two files drifting apart.
