Done. The file `/tmp/ws/index.html` is now created with a complete real-time fluid simulation. **Features:** - Full-screen canvas with fluid physics simulation - Click and drag to push swirling colored dye through the fluid - Real-time advection, diffusion, and pressure solving using Navier-Stokes equations - Dynamic color cycling that creates swirling patterns - Mouse and touch support for interaction - Self-contained with no external dependencies

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
