- Create single PhotoGrid component with columns (1,2,3,auto) and masonry options
- Remove 5 duplicate grid components
- Update HorizontalScrollPhotoGrid to HorizontalPhotoScroll with Photo type
- Add interactive test page for PhotoGrid
- Update all pages to use new unified component
- Use svelte-bricks for proper masonry layout
- Single column always uses natural aspect ratios
- Square thumbnails (object-fit: cover) for multi-column non-masonry layouts
