   Verification call — shared styling for the customer and agent pages.

   Deliberately the same design language as the rental app
   (halit-88.github.io/ez-rentals-app): white background, black text and
   buttons, same typography and controls. The call is a step inside that
   flow, so it must not look like a different product.
