A port of Conway's classic cellular automaton to gno.land. The full board
lives on-chain — every generation tick is a real transaction, shared state
for whoever is watching.

**Realm path:** `gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/life`

## How it works

The board starts as a 20×15 grid seeded with a glider. Anyone can call
`Step()` to tick the simulation, load a classic pattern, or sculpt cells
by hand. All state persists between blocks.

## Example calls

```bash
# Advance one generation
gnokey maketx call -pkgpath gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/life -func Step ...

# Jump 10 generations at once
gnokey maketx call -pkgpath gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/life -func MultiStep \
  -args '10' ...

# Load the classic glider (top-left corner)
gnokey maketx call -pkgpath gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/life -func LoadPreset \
  -args 'glider' ...

# Paint a live cell at (5, 5)
gnokey maketx call -pkgpath gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/life -func SetCell \
  -args '5 5 true' ...

# Resize to a 30×20 board (clears state)
gnokey maketx call -pkgpath gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/life -func Reset \
  -args '30 20' ...
```

## Presets

| Name | Type | Period | Notes |
|------|------|--------|-------|

| `blinker` | Oscillator | 2 | Simplest oscillator |
| `toad` | Oscillator | 2 | Two-row alternation |
| `beacon` | Oscillator | 2 | Two interlocked blocks |
| `block` | Still life | — | Stable 2×2 square |
| `pulsar` | Oscillator | 3 | Large symmetric pattern |
