   Phase 2: Dual-UPS dashboard

   Purpose:
       Arrange independently monitored UPS cards in a balanced
       two-column desktop layout.

   Design decisions:
       - Each UPS remains a self-contained card so a failure of
         one device does not visually suppress the other.
       - Equal-width columns make the two power domains easy to
         compare.
       - Cards collapse to one column on narrower screens.
       - Unavailable devices remain visible with a clear error
         state rather than disappearing from the dashboard.
