double check tokens

https://developers.cloudflare.com/cloudflare-one/identity/authorization-cookie/validating-json/#javascript-example

Only an external Cloudflare JavaScript token-validation link is provided, and no repository file, test, or code location is named. Start by reading that document, then locate the token-related auth flow in the project’s TypeScript/JavaScript code and identify where verification is done. Done looks like implementing or documenting behavior that is clearly aligned with the linked reference and can be verified from the code.
