**Planning index creation**

I need to create an index and make it polished. I'm thinking about implementing fullscreen controls on the canvas. It’s important to incorporate drag toggle semantics to avoid repeated cells. Responsiveness and accessibility are key; maybe I should include a speed slider generation as well. The user asked for something specific, so I’ll focus on building it efficiently and accurately. Let’s get started on making this come together!

**Inspecting potential bugs**

I need to investigate the bug with the pointer cell possibly being null when clicking outside the canvas. It seems that the index could theoretically be null too. Also, the click-drag toggles the mode based on initial settings, which seems good. I should check if there's an issue with Chromium being unavailable and validate everything. The user asked about building this, so I want to ensure my thoughts are clear and concise.

Created the self-contained Conway’s Game of Life app at: `/tmp/ws/index.html` Features: - Full-screen responsive canvas grid - Click-and-drag drawing - Right-click-and-drag erasing - Play/pause, single-step, randomize, and clear controls - Generation and live population counters - Keyboard shortcuts: `Space` to play/pause, `→` to step

EVALUATION

3/5 working

Conway's Game of Life simulator; drag draws cells, space/enter runs simulation, but visuals are sparse and minimal.

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.
