Build a 3D Lorenz-attractor visualization using the provided Three.js library. 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. Use the provided `three.min.js` (global `THREE`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Integrate the Lorenz system with sigma = 10, rho = 28, beta = 8/3, and initial state (0.1, 0, 0). Use a stable numerical time step. - Draw a luminous-looking, colored trajectory progressively as the system evolves, revealing its two-lobed butterfly shape. Keep trajectory storage bounded; actual bloom postprocessing is optional. - Frame the full attractor initially. Dragging orbits the camera around it, and the mouse wheel changes camera distance without entering the geometry. - Provide Pause/Resume and Reset. Pause freezes trajectory growth while camera controls remain usable; Reset clears the trail and restores the initial simulation state. - Only the core global THREE library is provided. Implement camera interaction without importing unavailable addons. Verify: Sample trajectory growth, orbit the camera, and check that the existing trail remains connected and visible from the new angle. Pause growth while moving the camera, then reset and check that the trail starts again from the initial state.

The Lorenz attractor visualization is now running, but the 3D scene is not visible due to the lack of initial trajectory points. Let's improve the visualization by: 1. Adding a more noticeable trail color and thickness. 2. Adjusting the camera position and lighting for better visibility. 3. Ensuring the trail is drawn progressively and smoothly. I'll update the code to address these issues.

The error occurred because the variable `depth` was incorrectly reused. Let's fix that and also enhance the visualization by adding a few more points to the trajectory initially to make the attractor visible.

Let's simplify the approach and add some initial points to the trajectory to make the attractor visible right away. I'll directly add a few points to the `trajectory` array at the start of the animation.

The error persists due to a lingering `depth` variable issue. Let's fix the entire `updateTrail` function to ensure no variable conflicts and make sure the Lorenz attractor is visible.

Let's simplify the entire `index.html` file to ensure everything is correct. I'll rewrite the relevant parts to ensure no conflicts and the Lorenz attractor is visible.

The Lorenz attractor is now visible, though the error about `NaN` values suggests there might be numerical instability. Let's refine the simulation to ensure stability and improve the visualization by adding a small epsilon to avoid division by zero and ensure smoothness. I'll update the Lorenz equations and ensure the trail is correctly rendered.

The error about `epsilon` being already declared suggests there might be a misplacement. Let's simplify the approach and ensure the Lorenz attractor is stable and visible. I'll remove the problematic epsilon logic and focus on ensuring the simulation is stable.

The error message "Assignment to constant variable" suggests there might be a problem with how the state is being updated. Let's ensure the state is mutable and the simulation is correctly updating the trajectory. I'll make sure the `state` object is updated properly and ensure the trail is correctly rendered.

The Lorenz attractor is visible, but the `NaN` error persists, indicating numerical instability. Let's address this by ensuring the simulation is stable and the trajectory is correctly rendered. I'll add a check to prevent `NaN` values and ensure the simulation is robust. I'll refine the simulation by adding a small epsilon to avoid numerical instability and ensure smooth rendering.
