Requirement: Batch canvas insertion uses viewport flow layout
Batch canvas insertion SHALL place inserted items left-to-right using the current canvas viewport width in canvas coordinates, then wrap to a new row when the next item would exceed that width.
For media items inserted through the batch path, the final insertion size SHALL remain stable for the batch flow and SHALL NOT be rewritten after load in a way that changes the batch spacing.
Scenario: Wide viewport fits multiple items on one row
- GIVEN the current canvas viewport can fit multiple batch items at the active zoom
- WHEN a batch insertion runs
- THEN items SHALL be inserted left-to-right on the same row until the next item would exceed the viewport width
Scenario: Narrow or zoomed-in viewport wraps items
- GIVEN the current canvas viewport cannot fit the next batch item at the active zoom
- WHEN a batch insertion runs
- THEN the next item SHALL be inserted at the batch start x coordinate on the next row
- AND the next row SHALL start after the tallest item in the previous row plus the configured vertical gap
Scenario: Batch insertion scrolls to the batch center
- GIVEN one or more items were inserted by a batch insertion
- WHEN insertion completes
- THEN the canvas SHALL scroll toward the center of the inserted batch bounds
Scenario: Batch media sizes stay stable
- GIVEN image or video items are inserted through the batch flow
- WHEN the media finishes loading
- THEN the batch spacing SHALL remain based on the original batch layout size
- AND later media resizing SHALL NOT shift the row spacing for the completed batch
