 A symmetric encryption module implementing AES-256-GCM with Argon2id key derivation, following established envelope encryption patterns (similar to JWE/Fernet). Payloads are self-contained JSON blobs — no shared state or config files required to decrypt.
 
 Built to understand authenticated encryption, KDF parameter binding, and defensive input validation from first principles rather than wrapping a high-level library.
