Paid: Provably-fair Solana vanity keypair + signed receipt

Grind a fresh Solana keypair whose Base58 address matches a chosen prefix/suffix, with a commit–reveal receipt signed by the service key (published at /.well-known/three-vanity.json) so the buyer can prove the key was ground fresh and never kept. Pass sealTo=<X25519 pubkey> to ECIES-seal the secret. Difficulty-tiered $0.02–$0.40; combined pattern ≤3 Base58 chars; settlement runs only after a successful grind.
