# sprite Demos

## Minimal Valid Sprite

A 3x3 sprite with an inline palette demonstrating the minimum required fields.

<div class="demo-source">

```jsonl
{"type": "sprite", "name": "square", "size": [3, 3], "palette": {"{_}": "#00000000", "{r}": "#FF0000"}, "grid": ["{r}{r}{r}", "{r}{_}{r}", "{r}{r}{r}"]}
```

</div>

<div class="demo-container" data-demo="basic">
</div>

## Sprite Color Count

Verifies palette color count is correctly reported.

<div class="demo-source">

{"type": "sprite", "name": "square", "size": [3, 3], "palette": {"{_}": "#00000000", "{r}": "#FF0000"}, "grid": ["{r}{r}{r}", "{r}{_}{r}", "{r}{r}{r}"]}
```

</div>

<div class="demo-container" data-demo="colors">
</div>

## Sprite Dimension Verification

<div class="demo-source">

```jsonl
{"type": "sprite", "name": "square", "size": [3, 3], "palette": {"{_}": "#00000000", "{r}": "#FF0000"}, "grid": ["{r}{r}{r}", "{r}{_}{r}", "{r}{r}{r}"]}
