What changed

• Added a new implementation spec for picture_16 focused on CheckoutSummary when the checkout payment method is TRANSF.
• Defined the scope on top of the existing transfer summary flow, centered on:
  • src/components/Plans/Checkout/CheckoutSummary/CheckoutSummary.js
  • src/components/Plans/Checkout/CheckoutSummary/TransferInformation/index.js
• Documented that the new layout should support transfer flows for Argentina, Mexico, and Colombia.
• Explicitly defined that the payment process steps also apply to ar, mx, and co, with a shared layout and country-specific bank/fiscal information.
• Captured the current business/UX constraints to avoid arbitrary implementation decisions, including:
  • fallback behavior for unsupported countries or upgradePending = false
  • no copy-to-clipboard behavior in this first iteration
  • no invention of non-versioned assets for the banking block iconography
  • explicit pending business data still needed for Mexico and Colombia transfer account details
• Added the picture_16 asset to the repository for traceability from design to implementation.

Open questions / follow-up

• Product/business still needs to confirm the exact transfer account/instruction data for Mexico and Colombia before implementation, since the provided image only shows Argentina-specific account data.
