Problem / Context

Planned improvement: the public SDK hooks were copyable, but App mixed orchestration, financial eligibility and all UI. No incident was identified. Integrators need a complete reusable folder for private transfers.

Live demo

Open the main Cloudflare demo - see the interface before copying the integration.

Open the public Cloudflare preview - no authentication required.

Changes

• App is now a 61-line demo shell. Copy src/invisible/ for the controller, complete widget or individual display modules.
• Keep one session owner, existing SDK hooks and mutation protection. Headless refund actions require fresh, matching, nonterminal eligibility.
• Scope styles to the widget and use unique dialog/popover/radio identifiers for multiple instances. Preserve inline destination input and custom payout options.
• Document interfaces and customization. No new dependencies.

Validation

• 30 tests passed; TypeScript and production build passed; dependency audit found zero vulnerabilities.
• Copied the folder into an independent production-built host: two widgets keep separate input/selection/IDs; host styles remain intact. Brave desktop/mobile and keyboard checks passed, including native review focus, Escape and local confirmation.
• Mocked SDK checks cover uncertain refund/reconnect protection, terminal states and unrelated snapshots; existing exact payout payload and mutation tests remain green.
• Live coordinator connection currently reports WS_HANDSHAKE_FAILED. No funded transfer or settlement was verified.
