// The browser wallet against the PHP one.
//
// Sirius Press has two independent implementations of the same cryptography:
// PHP on the server, which verifies, and JavaScript in the page, which signs.
// If they disagree by one byte, nobody can log in — and the error will look
// like a rejected password rather than a hash mismatch, which is a miserable
// thing to debug at three in the morning.
//
// So this compares them directly. Every vector is the output of the other
// implementation, not of this one.
//
//   node tests/interop.mjs
//
// Needs no dependencies: the wallet is loaded as plain source, with `window`
// pointed at the Node global so WebCrypto is found where the browser puts it.
