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 `index.html` (single self-contained file, no external assets/CDNs) — an interactive 2D aquarium-breach simulation on canvas. **Implemented:** - Intact glass tank with water, 4 fish, sinking rocks + a small movable pebble, 3 anchored plants, and a floating rubber duck; glowing crack handle on the right glass, draggable vertically below the waterline (plus a synced slider). - **Breach:** right panel shatters into rotating glass fragments (drag/resistance in water, gravity + floor collisions outside), water exits as a gravity-curved jet with an immediate spray burst, waterline falls continuously, and Torricelli-style outflow weakens as the level nears the opening and stops at it. - Escaped water forms a puddle that spreads across the floor, constrained by the room walls. - Current model: plants bend with the current, fish swim against it (stronger fish hold position, weaker ones get swept through the opening and then fall/flop under gravity), the duck floats/follows the falling surface and can be drawn to the opening, and small movable objects that fit the opening can be carried out. Objects outside transition to gravity, floor collision, and puddle swimming/floating. Live HUD shows tank %, outflow, puddle volume, and escaped count. **Reset** restores the exact initial scene. **Actually checked in the browser:** - Initial intact scene renders correctly (no console errors). - Dragged the crack handle down (verified readout changed to y=462), pressed **Breach**, and sampled early outflow: jet immediately visible, arcing downward to the floor. - Confirmed waterline falling (100% → 90% → 78%), outflow weakening (41 → 33 L/s), puddle spreading, plants bending toward the breach, shards accumulating on the floor, a fish swept out onto the floor (escaped counter = 1), and the duck pulled to the opening. - Pressed **Reset** and verified the tank returned intact: 100% water, crack back at y=400, no puddle, Breach re-enabled. **Remains unverified:** the complete drain-to-stop end state (level reaching the opening) and a full duck/pebble exit were trend-verified (weakening outflow, duck at the opening with the exit threshold fixed) but not observed to completion within the time budget, since draining takes ~20s.
