Conway's Game of Life - Frontend only

Files:

• index.html — main page
• style.css — styles
• script.js — game logic and UI

How to run:

1. Open index.html in your browser (double-click or use a simple static file server).
2. Use the controls to Start/Stop, Step, Randomize, or Clear.
3. Click or drag on the canvas to toggle cells. Adjust speed and cell size with sliders.

Notes:

• No backend required.
• For best results, open the page via a local server (e.g., python3 -m http.server) if your browser blocks local file scripts.

New features:

• Presets: select common patterns (Glider, Lightweight spaceship, Pulsar, Gosper glider gun) from the Presets dropdown.
• Wrap edges: enable "Wrap edges" to use toroidal neighbor rules (cells at edges consider opposite edges as neighbors).
• Save / Load: Save the current grid to your browser's localStorage (client-side only) and load it back later. The save is stored per-browser and per-machine.
• Speed slider: slider direction matches natural expectation: left = slower, right = faster.
