Source | 1200 × 1600 | Aspect ratio 0.75 | Observed: __________ | Next decision: __________
Matching placement | 900 × 1200 | Scale uniformly to 75 percent | Observed: __________ | Next decision: __________
Square contain | 1200 × 1200 | Design becomes 900 × 1200 with side space | Observed: __________ | Next decision: __________
Square cover | 1200 × 1200 | Crop 400 pixels of total source height | Observed: __________ | Next decision: __________

Review steps:
1. Open Luma and choose Mockup in the studio menu. Keep an unmodified copy of the artwork and note its width and height.
2. Choose the placement and inspect whether the design is cropped or stretched. Use recognisable circles or lettering to expose distortion.
3. Download a test if the current workspace permits it and inspect the downloaded file separately. A working download and a correct on-screen preview are different checks.

Decision note: These are placement calculations, not a photographed product or a new Mockup export. The earlier browser test produced a PNG despite a blank preview. A mockup cannot establish print colour, physical fit or manufacturing accuracy.
