{{--
    Responsive payment checkout shell: bottom sheet on mobile, centered modal on desktop.

    Audiences:
      - buyer (default): public ticket buyers, donors, shoppers — self-serve checkout
      - operator: signed-in staff flows such as wallet top-up

    Optional overrides: $sheetTitle, $sheetSubtitle, $sheetFooter, $sheetAria, $iframeTitle
    Requires Alpine ancestor with:
      - showSheet (bool)
      - checkoutUrl (string) — authorization / waiting URL
      - accessCode (string, optional) — Paystack initialize access_code for Inline
      - publicKey (string, optional) — unused by resumeTransaction; kept for callers
      - returnUrl (string, optional) — where to go after Inline onSuccess (?reference=)

    Paystack checkout.paystack.com cannot be iframed (X-Frame-Options: SAMEORIGIN).
    Primary path: Paystack Inline JS (PaystackPop.resumeTransaction) — in-page overlay,
    not a separate browser tab. Same-origin URLs (e.g. MoMo waiting) still use iframe.
