   AI Meeting — visual theme aligned with kb.tokenwave.cloud/ds

   Approach: override Arco Design CSS variables for colors / radius,
   then add a small set of DS-style utility classes (.ds-*) that our
   components use for layout primitives (page head, metric row, running
   banner, empty state, etc.). No Tailwind; plain CSS only.
