When Paystack Inline is ready: widen desktop panel for channel sidebar, collapse
to a minimal header, hide footer trust line, and re-pin the checkout iframe to
the sheet body so it does not read as a second modal on top of Ladill chrome.
Redirect Paystack iframes into the bottomsheet/modal body (where the spinner
is) instead of allowing a second full-viewport Paystack modal on top. Hide
Paystack background dimmer; keep Ladill header/close chrome.
Pre-set allow=fullscreen on Paystack iframes before navigation (createElement
hook + MutationObserver on allow/src/id), re-apply if Paystack overwrites
allow, and send Permissions-Policy HTTP headers so checkout.paystack.com can
use fullscreen inside the in-app sheet.
Stop form POSTs from 307ing to ladl.link or redirecting away to
checkout.paystack.com, open Paystack Inline with access_code, and use
the single-chrome sheet so payment stays on the Mini page.
Paystack blocks iframes, so checkout uses a popup beside the sheet/modal chrome. Opening about:blank on the user tap keeps that window from being blocked after the async initiate response.
Paystack checkout.paystack.com returns X-Frame-Options: SAMEORIGIN, so the shared sheet opened empty. Keep mobile sheet/desktop modal chrome, launch checkout in a named window with a Continue CTA fallback, and escape payment-return via window.opener or top.
