/* ==========================================================================
   FinBedrock calculators — widget styles (BEM, prefix fbc-).
   Variables are scoped to .fbc-root (never :root) so nothing leaks into the
   theme. Dark palette follows the site's own switch (Kadence colour switch /
   data-theme), like the research pages; prefers-color-scheme alone does not
   flip it, so the widget never turns dark on a white page.
