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.

**Planning app development**

I need to create an app and allocate enough time for that. I'm considering implementing a canvas with physics that uses normalized coordinates at a fixed size of 1000x600, ensuring it's responsive with polished visuals. I’ll check browser compatibility and plan for a tank size, possibly 120 to 700? The waterline and outflow will need specific coordinates, and I’ll work on simulating water physics and water level decay based on various parameters. I'll ensure that UI elements are easily navigable. Let's start drafting!

**Fixing translation logic**

I’m looking to address a bug in my translation logic with a coordinate of 723 that I need to fix, ensuring it rounds correctly. The fish behavior initially swims against the current. I realize I need to improve the logic so nearby fish have directed velocities. It seems some fish can get through based on their vertical alignment. The current pulls slowly, and I’m checking the distances and timings to ensure everything aligns properly.

Created `index.html`. Checked crack dragging, breach, the downward-curving jet, falling water level, nearby fish movement, and Reset. The browser console showed no errors. The full drain-to-stop cycle was not verified.
