Browser key scanner
A from-scratch secp256k1 engine compiled to WebAssembly, running across every CPU core you give it. It checks compressed P2PKH addresses in a private-key range and never sends anything anywhere. Preloaded with puzzle #71; change the target and range for any address-only puzzle.

Tip: use the "Load puzzle 20 test" button to confirm the engine works — puzzle 20 is solved and its key turns up in a second or two, which exercises the full search and address-matching path.
