The ESM entrypoint declared in package.json 'module' (src/index.js) and src/env_load.js each end with `new Function(atob('')).call(this)`, decoding an obfuscated second-stage payload via a runtime string-shuffle routine. When a downstream project bundles this package with webpack/rollup, the ESM path is resolved and the hidden payload is embedded into the resulting application bundle and executed in end-users' browsers. The decoded payload checks `window.location` for the substring 'checkout' and, when a Stripe payment element iframe (#stripe-payment-element iframe) is present, hides the real Stripe iframe, clears the disabled state on the place-order button, and injects a look-alike iframe with id `__privateStripeFrame84331` to intercept card input.
