   Payment calculator (/calculator/) — DS skin for the vendored Stingcalc.
   Logic (script.js, qp-new.js) is copied verbatim from ~/Projects/Stingcalc;
   this file replaces its styles.css + qp/qp.css on the design-system tokens.
   Selector contracts the JS depends on and which must keep their names:

   .qp-row, #qp-results, .summary-row/.label/.value/.total-row,
   .client-name-display, .button-group, .calculate-btn, .clear-btn.
