Run Conway's Game of Life on a full-screen canvas grid with click-and-drag to toggle cells, plus play/pause, step, randomize, and clear controls.

The user wants a Conway's Game of Life implementation as a single-page web app in one self-contained `index.html` file. Let me plan the features:

1. Full-screen canvas grid
2. Click-and-drag to toggle cells
3. Play/Pause button
4. Step button
5. Randomize button
6. Clear button
7. All CSS in `<style>` tag, all JS in `<script>` tag
8. No external resources whatsoever

Let me build this out with a clean, polished design.

Let me verify the file exists and looks correct.
bash {"command":"ls -la /workspace/index.html"}

The file is created. Let me verify the content looks good by doing a quick sanity check.

Done. `/workspace/index.html` has been created — a fully self-contained, zero-dependency Conway's Game of Life. Here's what's included: **Grid & Rendering** - Full-screen canvas that auto-sizes and resizes with the window - Subtle grid lines with highlighted alive cells (cyan gradient) - Grid lines drawn over background, cells drawn on top **Controls** | Button | Shortcut | Action | |--------|----------|--------| | ▶ Play/Pause | `Space` | Toggle simulation | | Step | `S` | Advance one generation | | Random | `R` | Randomize 27% density | | Clear | `C` | Kill all cells | | Speed slider | — | 1–60 fps | **Interaction** - **Click & drag** to toggle cells on/off (paints in the direction of each drag) - Touch support for mobile **Info bar** shows generation count, population, and grid dimensions. Everything lives in the single `index.html` with zero external requests.

TAKE IT TO CODE

A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.

EVALUATION

4/5 working

Game of Life grid renders and simulates correctly via space/enter to play; click/drag/wheel toggling barely visible but generation counter advances properly.

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
