## Goal

Ship the user-rights surface end-to-end: DSR endpoints that walk Epic A's PII tags to export/delete/rectify/restrict any subject's data, per-use-case consent gates with audit-logged proof, and a compliant cookie consent banner with EU-prominence defaults.

## Why

Epic A delivered declarative PII inventory + retention + sub-processors. Epic B closes the remaining gaps: GDPR Arts. 15–18 + 20 DSR endpoints, Art. 7 demonstrable consent with structural lint enforcement, and a CNIL-compliant cookie consent banner that downstream consumers can drop in without forking legal-compliance logic.
