/* ============================================================================
   niswosakit · checkout.css — styling for the shared on-page checkout modal
   (the Stripe Payment Element modal + custom keypad built by checkout.js).

   This is the portable companion to checkout.js. The /vote pages carry these
   same rules inside their own styles.css and do NOT load this file; every
   OTHER page gets the modal styling from here (loaded by support.js when it
   wires up Stripe), so the checkout looks identical everywhere.

   The modal renders in its own warm-card theme, scoped to the overlay roots,
   so it reads correctly whether the host page is dark (methodology, sources,
   how) or light. It never inherits — or disturbs — the host page's palette.
   Faithful copy of the approved /vote modal (Website/Pages/vote/styles.css).
