Educational BIP-39 visualizer with Counter-Strike 1.6 UI (cs16.css).
Pipeline: entropy → SHA-256 checksum → 11-bit groups → BIP-39 wordlist.
Generate uses browser CSPRNG for demos only. Real keys: physical entropy offline.
Concept: bip39-visual (bitpanter). Skin: cs16.css (ekmas). MGS1 fonts: gleeson (CC BY-SA 4.0).
