## 🎯 שאלה

**Google Photos masonry grid — תומך ב-A2UI?**

---

## 🏆 Verdict: **כן** — ב-CSS Grid masonry + virtualization

---

## 📸 Google Photos · Layout

```css
.photo-masonry {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(180px, 1fr));
  grid-auto-rows: 180px;
  gap: 4px;
}

/* Different heights based on aspect ratio */
.photo-tall { grid-row: span 2; }
.photo-wide { grid-column: span 2; }
.photo-large { grid-row: span 2; grid-column: span 2; }
```

### A2UI representation
```json
{
  "id": "photos-grid",
  "component": "PhotoMasonry",
  "tileMinSize": 180,
  "gap": 4,
  "items": {
    "template": "photo-template",
    "data": "/photos"
  }
}
{
  "id": "photo-template",
  "component": "PhotoTile",
  "src": { "path": "{item.thumbUrl}" },
  "aspectRatio": { "path": "{item.aspectRatio}" },
  "tall": { "path": "{item.aspectRatio < 0.7}" },
  "wide": { "path": "{item.aspectRatio > 1.5}" }
}
```

### Performance
- 100K photos in album → virtualization mandatory (Round 22 mitigation)
- LCP image preloaded
- Date headers sticky (scroll-driven CSS)

### Cost
$0 — pure CSS Grid + intersection observer.
