   INNO BRAIN — Business section
   Everything here is prefixed .biz- so it cannot collide with the rest of the
   dashboard. Colours come from the same tokens as every other screen, so the
   accent picker moves this section too.
   The global prefers-reduced-motion rule in core.css already tames all of it.
