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.

**Preparing for build inspection** I need to focus on building things up, but first, I should inspect the existing files. It's important to ensure everything's in order before moving forward. I'll take some time to review the files I have, maybe even check for any issues that might need fixing. It's always better to be thorough and make sure the foundation is solid. I'm curious about what I might find, so let's dive in!

**Planning interface design** I need to create a comprehensive canvas interface that’s responsive. I’m thinking of implementing a drag crack slider along the vertical side below the waterline, probably using mouse drag functions to move it. This will require considering the right state management and physics for smooth interactions. I’ll need to write out the plan and details to ensure everything flows well together. Let’s figure this out step by step!

**Evaluating draggable coordinates** I need to figure out the right coordinates for dragging the right wall on the canvas display. It seems like the canvas has an actual width of 1120, and I can interact around coordinates (830, 420). However, I’m seeing a contradiction with the draggable condition where the y-value must be greater than the water line, which is causing issues with the visibility of the crack. It looks like I might need to adjust the initial opening position to below the water line.

**Checking draggable coordinates** Alright, I’m figuring out the draggable coordinates on the canvas. The x-coordinate at 796, when combined with the viewport, gives me that left side at 836. For the y-coordinate, adding 125 to 462 equals 587. Now, it seems like the draggable y is above 568; that’s good. I think I might click around x826, which is within 38 of my target, and then drag down to y600. Let's see how that goes!

**Evaluating water levels** I’m focusing on the water levels and initial settings. It looks like we’re starting with a target of 200 for the water level, with an opening set to 340. Everything is underwater except for the toy, which is at 230, and that seems correct. The current water level reads at 323, so I think I need to set the water to 205 and adjust the opening to 350. I also noted the tank level at 490.

**Adjusting draggable coordinates** I need to focus on dragging coordinates correctly for the crack center on the canvas. The desired y-coordinate range is between 223 and 460, and it should be able to drag up to y510 while keeping the x-coordinate fixed at 828. The final coordinates should reflect those constraints to ensure everything aligns properly on the canvas. I'll make sure to follow these guidelines while working on the draggable properties!

**Considering browser behavior** I'm thinking the browser looks good early on, but is there an issue with the water level not falling? It shows the level exactly at 285 after I clicked, which might happen immediately. Should I wait and try to reload with a screenshot? It seems like a screenshot from the browser might not have any delay, but I'm wondering about potential motion effects. There's a lot going on here!

**Considering toy and current** I've observed that the toy fell to the floor outside, and I think the current may not be strong enough for its buoyancy in the water. I'm also wondering if it's excited or how it fits in this situation. I guess I need to evaluate everything properly and do a reset check to see if everything is functioning as it should. Let's figure this out!

Created the self-contained canvas simulation in `index.html`. Verified in-browser: - Dragged the highlighted crack to a new position below the waterline. - Triggered the breach. - Observed curved downward jet, falling waterline, glass fragments, spreading floor puddle, and object/current response. - Used Reset and confirmed the intact initial aquarium returned. No external assets or network requests are used.
