revert from Pyodide → vanilla JS (faster) + 3 fixes
Browse filesUser feedback: Pyodide too slow to load, prefers JS.
- Drop Pyodide entirely (no numpy WASM, no 5s cold load).
- Switch coupling formula: shared sin(t) + per-stream noise (no XOR).
High coupling now produces clean diagonal scatter alignment instead of
the zigzag pattern the XOR was creating.
- Slow tick from rAF (60+ fps) to setInterval(33ms) — ~30 fps, plenty for
the visualization, less GC pressure.
- EMERGENT badge: opacity 0 + visibility hidden when MI ≤ 0.30 (was
opacity 0.15, looked always-on faintly).
Rolling 250-sample buffer for stable MI estimates; metrics start updating
after 50 samples (~1.7 s warmup).

- Vanilla JS — `setInterval` 30 fps tick over a 250-sample rolling buffer.

- Engine: shared `sin(t)` + individual gaussian-ish noise per stream.

`L = (1−c)·noiseL + c·sin(t)`, `R = (1−c)·noiseR + c·sin(t)`. High coupling
|
| 32 |

collapses both streams onto the diagonal — the scatter aligns cleanly.
|

- 12-bin histogram entropy over `[−1.5, +1.5]`. EMERGENT badge shows only

when MI > 0.30 (`opacity:0` + `visibility:hidden` otherwise — fully gone).
