   Each provider lays out its own buttons inside its iframe, so the 2×2
   grid comes from the providers (Stripe's auto layout, PayPal's
   "Horizontal" layout setting), not from CSS. Only spacing and visibility
   of the outer wrappers are styled here — never colours, shape or
   anything inside an iframe. Button theme/colour/radius are WooPayments
   and PayPal admin settings; see docs/design-system-code.md.

   Empty providers: WooPayments hides the element and drops .is-ready when
   no wallet is available; PayPal leaves its container without an iframe.
   Every margin below is conditional on the provider actually rendering,
   so a missing provider leaves no gap. :has() unsupported → no label
   and plain stacking, never a broken layout. */
