/* ============================================================
   VeriSpace GLOBAL BASE STYLES
   Apple-inspired look for ALL default Bootstrap 5 elements.

   WHERE TO PUT IT: at the very TOP of style.css, above your page styles.
   (style.css must load AFTER bootstrap.css.)

   Why it is safe: your page styles (.vs-catalog-page, .vs-payment-page ...)
   are more specific AND come later, so they keep winning.
   Nothing of yours is changed. Everything here uses variables, which is
   what makes dark mode possible (see vs-dark.css).
