/* tools-core.css -- shared foundation for the new PHP/full-width "advanced
   dashboard" tool family (e.g. fan-power-configurator.php). Holds only the
   generic primitives every such tool needs (field/input/select, segmented
   switches, cards, callouts) -- each tool's own layout (grids, flow
   diagrams, tables, charts) stays in its own dedicated CSS file.
   The classic .html calculators keep using tools.css and are unaffected. */
