+ * To guarantee absolute privacy:
+ * 1. The client browser NEVER has access to raw database tables or individual-level records.
+ * 2. Mathematical aggregations occur solely on the server-side.
+ * 3. Cohort minimum sizes (k-anonymity) are programmatically enforced at the API boundary.
+ * 4. Identification vectors are scrubbed using randomized keys and cryptographic hashes.
