/* HFB Tools — calculators.
   Themed to the husforbegyndere "Værksted" identity (graphite + spirit-level
   amber on warm concrete), with literal fallbacks so the calculator still looks
   right on a site that isn't running the child theme.
   Amber is too light to carry white text, so fills use dark ink on amber.
