+/**
+ * /go — payment redirect bounce page for D-Money web checkout.
+ *
+ * The redirect is done CLIENT-SIDE on purpose: the navigation must originate
+ * from the loaded https://edrpassenger.triaplc.com/go document so the browser
+ * sends `Referer: https://edrpassenger.triaplc.com` to D-Money. D-Money only
+ * whitelists that origin, so a server-side 307 (whose referrer on the redirect
+ * hop is browser-dependent and can be stripped) must NOT be used here.
+ *
+ * It fires immediately (no delay) and paints a bare white full-screen cover
+ * above the sticky header (z-[60]) — no portal chrome, no text on the happy
+ * path. A short message shows only when the link is missing/untrusted.
+ *
+ * `?url=` MUST be percent-encoded by the caller (Uri.encodeComponent() in the
+ * Flutter app / encodeURIComponent() on web); otherwise the query parser
+ * truncates the D-Money URL at its first `&` and merch_code/sign are lost.
+ * See scripts/test-go-redirect.mjs.
