Prompt for this run

Build an interactive 2D aquarium-breach simulation on a 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: - Initially show an intact glass tank containing water, fish, rocks, plants, and a floating toy. Let the user drag a visible crack vertically on one side below the initial waterline, then press Breach. Provide Reset to restore the same initial scene. - On Breach, show the panel breaking around the selected opening. Water exits in a gravity-curved jet, and the waterline falls continuously. Outflow weakens as the water level approaches the opening and stops when water no longer reaches it. - Escaped water forms a spreading puddle constrained by the floor and room walls. - Model distinct responses to buoyancy, drag, and current: rocks sink, the toy floats, plants bend or drift, and fish initially swim against the current before some are swept through the breach. Movable objects that fit the opening can be carried out by the flow. - Objects leaving the water transition to gravity-driven motion and collide with the floor. Glass fragments rotate, collide, and experience resistance in water. - Simplified, internally consistent physics is sufficient; a full computational-fluid-dynamics solver is not required. Verify: Position the crack, trigger a breach, and sample the early outflow. Check that the jet curves downward, the waterline begins to fall, and nearby objects respond to the current. Use Reset and check that the tank returns to its intact initial state.

I'll create a self-contained `index.html` file that implements an interactive 2D aquarium breach simulation as described. The app will feature: - An initial scene with water, fish, rocks, plants, and a toy. - A draggable vertical crack on one side below waterline. - A "Breach" button to initiate water outflow through the crack. - Water rushing out with a curved jet, waterline falling, and objects reacting to flow. - A "Reset" button to restore the initial state. I'll embed all CSS and JavaScript inline for portability and simplicity. Let's proceed with building this file.

I have created a complete `index.html` file implementing the requested aquarium breach simulation. You can open this file in a browser to interact with the scene: - Drag the red crack marker vertically on the right side. - Click "Breach" to start water outflow. - Observe the water jet, falling waterline, object reactions, and puddle formation. - Click "Reset" to restore the initial scene. Would you like me to display the contents or assist further with test instructions?
