Prompt for this run

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.

Need to build index.html with 60x40 grid canvas, finite boundaries. Controls: Play/Pause, Step, Randomize, Clear, generation counter. Start paused with blinker. Click/drag painting logic. Fit viewport.

Implement canvas with devicePixelRatio scaling. Grid 60 columns, 40 rows. Cell size computed to fit.

We need to write file, then test with browser tool.

Let's craft index.html.
