📝 Walkthrough

Walkthrough

This pull request makes three targeted changes across the platform services: (1) enables JWKS rotation on token generation errors in the Convex authentication plugin, (2) removes explicit item-level schema constraints from the recommendations array in the Loopi product recommendation workflow, loosening the schema structure, and (3) refactors the Vite inject-env plugin to load environment variables during the config resolution phase rather than at transform time, precomputing the environment object for HTML injection.
