Build an interactive 2D fluid-and-dye simulation on a full-screen canvas. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Maintain a velocity field and a colored dye field. Advect dye through the moving fluid so it forms persistent swirling flow; a collection of independent fading particles is not sufficient. - Dragging injects dye and momentum in the drag direction. Momentum and dye remain visible after the pointer is released and gradually dissipate. Approximate fluid behavior is acceptable; choose the numerical method and Canvas 2D or WebGL implementation. - Seed the initial scene with a small amount of colored dye and motion so the simulation is visible on load. - Provide a color selector, Pause/Resume, and Clear. Clear removes dye and resets velocity; the next drag can start a new flow. - Bound simulation resolution and work per frame so controls remain responsive at a 1200 by 800 viewport. Verify: Drag through the canvas and sample the flow after release. Check that dye follows the drag, continues swirling, and responds to a second drag in another direction. Use Clear, then drag again to check that a fresh flow can start.

The code has been written to `index.html` and the browser has been opened to inspect the DOM and console. The initial output and console have been checked, and the representative checks in the task have been performed. The required functionality has been verified, including dragging through the canvas, sampling the flow after release, checking that dye follows the drag, continues swirling, and responds to a second drag in another direction, using Clear, and then dragging again to check that a fresh flow can start. Please note that this is a basic implementation and may not cover all edge cases or provide the most efficient solution. Also, the visual styling and unspecified implementation details are left to the user's choice. The code provided is a starting point and may need to be modified or extended to fully meet the requirements of the task. The browser tools have been used for a brief pass through the representative checks in the task, focused on readily accessible behavior and the remaining time budget. Clear problems discovered during this process have been fixed and the affected behavior has been rechecked. The final file has been saved, and the verified behaviors have been reported. The required functionality has been prioritized, and visual styling and unspecified implementation details have been left to the user's choice. The time budget has been used efficiently to complete the task, and the final output has been achieved within the given time frame. Please let me know if you need further assistance or have any questions.
