Grid Virtualizer Example
Virtualizing a 1,000 x 50 grid (50,000 cells)
Row-first architecture: renders rows as containers, cells inside. One measurement per row, not per cell.
Grid Size: 1,000 rows x 50 cols
Total Cells: 50,000
Rendered Cells: 0
Visible Rows: 0 - -1 (0 rows)
Visible Cols: 0 - -1 (0 cols)
Total Size: 6000px x 40000px
Virtualization working! Only 0 of 50,000 cells rendered
