The grid device in the mockup generator renders every tile as an empty placeholder. No image ever appears, and no error is raised.
Note this is the mockup generator's grid DEVICE, not the Grid Builder layer reported in #1061 — different surface, possibly the same underlying cause. Please don't close as a duplicate without checking both.
Steps to reproduce
1. Create a mockup with device 'grid'
2. Point its tiles at valid image files on the board
3. Render
Tested with 9 different valid image files, using both relative paths (/media/admin/<board>/<file>.png) and absolute URLs (http://localhost:18000/media/…). Every combination produced empty tiles.
Expected
Each tile shows its image, as every other mockup device does.
Actual
Every tile renders as an empty placeholder. The SAME absolute URLs work correctly as imageUrl on every other device, so the files, paths and permissions are all fine — it is specific to the grid device.
Context
The device is effectively unusable. We replaced the two specimens that needed it with flat mockups.
