I'll build a self-contained Navier–Stokes fluid sim on a full-screen canvas: mouse drag injects velocity and swirling RGB dye, all in one `index.html`.

The file was written successfully. Let me verify it exists and is complete. The user asked for a single self-contained index.html with no external resources - I've done that.
`index.html` is a full-screen, self-contained fluid sim (no CDNs or network). **What it does** - Stable Navier–Stokes on a grid (diffuse → project → advect) - Dragging injects velocity and RGB dye; hue shifts with motion so swirls stay colorful - Soft speed glow so vortices catch light - Dye slowly fades so the canvas doesn’t fill up **Controls** - Drag / touch to push dye - `R` reset - `Space` pause Open `index.html` in a browser and drag.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Fluid dye simulation renders idle black canvas until drag creates colorful swirling dye trails; click/keys have no additional effect.

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.
