40-product grid (8 rows × 5 cols). 32 live Amazon competitor thumbnails pulled from the SERP for "puppy joint supplement large breed", mixed with 8 Pawganix candidates: 4 Black-jar variants (v4 sticker mockup line) and 4 Green-jar variants (final label line). Apply blur to validate scroll-speed standout; reveal to confirm position of candidates.
Sharp pass: With blur OFF, look at the grid for 1 second, then ask: "Which 3 images pull my eye first?" Note where each Pawganix candidate ranks among the 40 once revealed.
Blur pass: With blur ON, repeat. The blur strips away text and detail — only color, silhouette, and contrast remain. A candidate that ranks top-3 in this view has true scroll-speed standout.
| Outcome (sharp + blur both) | Verdict | Action |
|---|---|---|
| Both ≥ top-3 in row of 5 | PASS | Ship to split-test |
| Sharp top-3, blur ≥ 5th | FAIL · text reliance | Remediate color/silhouette |
| Blur top-3, sharp ≥ 5th | FAIL · silhouette only | Sharpen label clarity |
| Both bottom half | FAIL · redesign | Don't ship |
