Saving the HTML?

Running here stays free. A saved rebuild uses three@0.170.0: keep ../vendor/three-r170.min.js beside it at that relative path, or allow a network connection for the CDN fallback.

Preview or live?Recorded preview is a captured loop. Run opens the real HTML in an isolated live sandbox.

Simplified: Water reflections are faked inside the water shader (sky, a wall colour per house and bridge outlines, no real mirror pass), so boats, poles and windows never show in the water. Buildings are boxes with procedurally painted facades, and the boat slides along the walls instead of crashing.

Checks

Known issue: The boat and rower are blocky primitives, which look toy-like next to the detailed canal.
