iGrant.io verifier frontend (OpenID4VP + DCQL)

When to use

Build the relying-party UI: request a verifiable presentation, let the user scan a QR (or use the same-device wallet), and show the disclosed claims and the verified decision the instant the wallet responds. Depends on igrantio-frontend-client (vendored at src/lib/ows/) and an igrantio-verifier-backend deployment. Issuer UI is a separate skill (igrantio-issuer-frontend).

Before you build: run the integrator intake in igrantio-ows-overview - environment, API key, tenancy, backend host, webhooks, frontend - one question at a time, a recommended default with each.
