last hash: —
How it really works: the miner searches for a nonce until the hash has enough
leading zero bits. More zero bits means a rarer stone. This practice lowers the target to
16 bits (SHA-256) so it stays fast on a phone; the real contract uses keccak256
with a 20–28 bit target, and mining is done by agents through
scripts/mine.js.
Rarity Tiers
