Build Conway's Game of Life on a canvas with a 60 by 40 grid and finite, non-wrapping boundaries. 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: - Apply the standard rules simultaneously: a live cell survives with two or three live neighbors, and a dead cell becomes live with exactly three. Treat cells outside the grid as dead. - Start paused with a visible blinker pattern. Provide Play/Pause, Step, Randomize, and Clear, plus a generation counter. - While paused, clicking toggles a cell. On a drag, choose painting alive or dead from the first cell and apply that same state to each visited cell, without repeatedly toggling it. - Step advances exactly one generation while paused. Randomize and Clear leave the simulation paused and reset the generation counter; Clear removes all live cells. - Fit the grid and controls within the viewport while keeping cells distinguishable. Verify: Step the initial blinker twice and compare its alternating arrangements. Paint a short stroke while paused and check consistent cell painting, then use Clear and confirm the grid and generation counter reset.

I have implemented Conway's Game of Life as requested. The simulation runs on a 60x40 grid within a canvas, with finite boundaries and all required controls. Verification steps performed: - Stepped the initial blinker pattern twice: The vertical blinker correctly alternates to horizontal and back - Painted a short stroke while paused by clicking and dragging: Cells were consistently painted alive or dead based on the initial toggle state - Used Clear button: Confirmed the grid was emptied and generation counter reset to 0 The implementation includes: - Standard Game of Life rules applied simultaneously - Initial blinker pattern centered on the grid - Play/Pause, Step, Randomize, and Clear buttons with proper functionality - Click and drag painting that maintains consistent state (alive/dead) across the stroke - Generation counter that updates appropriately All required behaviors are working correctly within the viewport constraints, with cells remaining distinguishable at 10x10 pixels each.
