Repair attempt on Spark / thinking off / seed 43 (abandoned). index.html here is the untouched output.

1. Line 370: `const water = new THREE.Mesh(...)` redeclares the `water` Float32Array from line 195 — a module SyntaxError, nothing runs. Renamed the mesh `waterMesh` (lines 370-372).
2. Line 447: `for(let x=0;x<N;i=y*N+x)` never increments x (ReferenceError on i, then an infinite loop). Changed the update clause to `x++`.
3. With both fixes the page loads, but the water state goes NaN (THREE computeBoundingSphere: radius NaN) and line 518 throws a TypeError every frame. Third error — stopped, per the lab's rule that more than two mechanical fixes makes the result ours rather than the model's.
