# Round 26 — Lottie ⊂ A2UI · The Animation Subset Proof

**Date**: 2026-04-30
**Status**: ✅ COMPLETE

## 🎯 שאלה

**Lottie JSON ⊂ A2UI? כלומר Lottie animation = A2UI catalog item?**

---

## 🏆 Verdict: **כן** — Lottie הוא A2UI catalog component עם data binding

---

## 🎞️ Lottie · ה-Schema המקובל

```json
{
  "v": "5.7.0",
  "fr": 60,
  "ip": 0,
  "op": 180,
  "w": 1920,
  "h": 1080,
  "layers": [
    {
      "ty": 4,
      "nm": "Headline",
      "shapes": [{ "ty": "tx", "d": { "k": [{ "s": { "t": "BREAKING NEWS" } }] } }]
    }
  ]
}
```

### A2UI wrapping
ה-Lottie JSON **כולו** הופך ל-property של A2UI component:

```json
{
  "id": "hero-anim",
  "component": "LottiePlayer",
  "src": "https://assets.clastop.app/lottie/breaking-pulse.json",
  "data_overrides": {
    "Headline.text": { "path": "/article/headline" },
    "BackgroundColor": { "path": "{theme.brand}" }
  },
  "autoplay": true,
  "loop": true,
  "speed": 1.0
}
```

ה-`data_overrides` מאפשר את הLottie אנימציה להחליף text + colors מ-A2UI data model. ה-LLM שולח את ה-overrides — ה-Lottie file נשאר זהה ב-R2.

### זה יוצר eco-system
- Designers create Lottie in After Effects
- Export Lottie JSON → upload to R2
- LLM references the Lottie + provides overrides
- Animation plays with article-specific data
