ℹ️ How this works

Each encryption operation generates a fresh 96-bit IV using crypto.getRandomValues. The IV is prepended to the ciphertext before base64-encoding, so decryption can recover it automatically. The demo key is obfuscated with XOR-fragment reconstruction (educational only — not production-grade key management).
