Browser-based QRNG demo — NIST SP 800-90B. Min-entropy is what an optimal guesser faces; Shannon is the marketing number. Slide the detector bias and watch them diverge. Von Neumann fixes bias but not correlation — feed it a correlated stream and watch it output garbage while claiming success. Real Toeplitz extraction over GF(2). No backends.
