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.

Built the interactive aquarium-breach simulation in a single self-contained `index.html` (23 KB, inline CSS/JS, no external resources). **Features implemented:** - Intact tank with water, 5 fish, rocks, plants, balls/shell/drift-plant, and a floating duck toy - Yellow crack handle on the right panel, draggable vertically below the waterline (plus a synced slider, clamped to the submerged range) - **Breach** breaks a jagged opening, spawns rotating glass shards (water-dragged inside, gravity/bounce outside), and emits a Torricelli jet: exit speed ∝ √head, particles curve downward under gravity - Waterline falls continuously, outflow weakens as the level approaches the crack and stops at the crack; escaped water accumulates as a wall/floor-constrained puddle - Distinct physics: rocks sink/stay, duck floats on the falling surface and can exit, plants bend with local current, loose small objects are advected, fish swim upstream with draining stamina bars until weaker fish are swept out; escaped objects/fish fall, bounce, and flop/float on the floor/puddle - Live HUD (waterline %, outflow, puddle volume, escaped count, status) and `window.__sim` state hook for programmatic sampling **Verified in the browser:** - Initial intact scene renders correctly (duck visibility clipping bug found and fixed) - Dragged the crack handle: y 390 → 305, slider/HUD synced - Breached at two crack heights: jet visibly arced downward, waterline fell from 100% (y=232) to ~70% (y≈327) over a few seconds, outflow decreased with head, puddle volume grew, 4 objects escaped, fish clustered/swam against the current at the left wall - Reset restored the intact scene: 100% water, 0 puddle/escaped, crack back at default y=390 **Not fully verified:** the very end of draining (flow fully stopping exactly at the crack over the full ~30 s run) and floor-collision detail at the bottom of the canvas, which sits below the browser viewport fold — the underlying code paths were exercised via the escaped-object/puddle counters, but not visually confirmed at the floor line.
