   PaySalaryLoan - general loan calculator (.psl-calc). Markup: templates/_calculator.php and
   tools/site/partials/calculator.html; behaviour: public/js/psl-calculator.js.

   Uses the psl-site.css tokens (--psl-*) and falls back to the same values, so it also renders on a page that does
   not load psl-site.css. Inputs on the left and the navy results panel on the right from 768px (Principal Amount, Interest Amount, highlighted Total Pay Amount); stacked on phones.
