LSB image steganography

Embed UTF-8 text into RGB least-significant bits and export a lossless PNG. Optional password XOR obfuscates the payload before embedding — all processing stays on-device.

LSB steganography is for privacy demos and low-visibility notes — not strong cryptography. Always export PNG (lossy JPEG re-encode destroys the payload). Password XOR is obfuscation only.
