/* Dedicated stylesheet for fan-power-configurator.php -- layout specific to
   this tool only (toolbar, dashboard grid, power-flow diagram, gauge,
   tables, charts). Generic input/switch/card/callout/result primitives live
   in the shared tools-core.css so future advanced tools reuse them instead
   of re-defining their own copies. */
