Stutter, fractal reverse, and phaser — three effects applied to the detected
loop of a real drum beat, each with buttons to A/B the original loop against
the processed version. Every effect is verified down to the individual
sample, not just by ear. Technically the page loads a golden WAV, takes the
loop region from loop.detect, and runs each effect through
applyQuantumOp on a fresh copy.
Badges are sample-exact: STUTTER must write the first-10 ms slice verbatim at
start + k·span (k=0..3); FRACTAL must equal a manual reverse of
the loop's first half with the rest untouched; PHASE must differ inside the
loop and stay bit-identical outside it (in-place containment). The phase
effect running at all proves the 2026-07-02 repair — parameters are now an
explicit options argument, not a window.phaserParams bus read
(it crashed headless before). Same asserts spot-run in Node pre-ship.
