+ * Demo: standalone "Pay with Square" checkout page (Phase 3 test harness).
+ *
+ * Auto-resolves to a Square-connected school so the card form actually renders.
+ * Pass ?school=Name to force one, and ?amount=25.00 to set the amount.
+ *
+ * In your real app, $school / $amount / $buyerEmail come from session + DB and
+ * you simply `require square-checkout-widget.php` with a $sqCheckout array.
