BLD-845 UAT fixture
Checkbox Assurance Rail review
Preview and staging only. This page loads /developers/checkbox/uat/sdk.js, which uses the same SDK builder as the public drop-in script while keeping /v1/checkbox.js behind CHECKBOX_WIDGET_ENABLED.
Use this to confirm the checkbox microbrand, iframe launch shell, responsive behavior, and event logging without publishing or enabling a public partner Trust Badge.
Operators can inject the seeded sandbox key and callback with SURFACE_KIT_DEMO_PK_AGE_GATE and SURFACE_KIT_DEMO_REDIRECT_AGE_GATE. If unset, the existing redacted placeholder keeps the fixture safe while still proving the SDK render path.
