Dice Entropy Forge

Roll 100 physical-style dice to gather ≥256 bits of entropy. Digits are concatenated and hashed with SHA‑256 (WebCrypto) to derive a Bitcoin wallet seed.

Entropy target: 256 bits (≈100 dice)
Each 6‑sided die contributes about log₂(6) ≈ 2.585 bits. 100 dice → ~258 bits of entropy, comfortably above the 256‑bit target. Randomness here uses your mouse/CPU timing for the demo; for a real wallet, roll actual physical dice and never trust a webpage with your funds.
