/* Calculator pages: the hub, each calculator page, and the calculator web
   components themselves. The components link this file inside their shadow
   roots, after their own <style>, so one stylesheet restyles all eight.

   Page rules are scoped to body.calc-page. Component rules are scoped with
   :where(.calculator), which adds no specificity: they replace each
   component's base styles (same selector, later in the cascade) but leave its
   modifiers alone (e.g. .result-card.loss keeps its colour).

   After changing this file, bump its ?v= in the <link> of every component
   (components/calculators and its de, es and fr folders) and on the English
   pages that link it, then run scripts/build-i18n.js for the localized pages. */
