/* ===========================================================================
   /tools — hub + the three free calculators.

   Additive layer only: tokens and base come from site.css, and the nav /
   footer / breadcrumb / card / table / calculator-field / result-row / FAQ /
   CTA composition comes from tint-laws.css, which every tools page also
   loads. Anything below is either new furniture (tool cards, pane rows, stat
   tiles, the cut-layout canvas) or a print sheet.

   Mobile-first. Nothing here may create horizontal page scroll: the wide
   elements are the cut-list table and the layout drawing, and both scroll
   inside their own .table-scroll / .tk-plan container.
