Start with the narrowest layout
Preview the cover beside its title at phone width. Check whether eyes, gestures or labels get too small. Watch for a duration badge masking a detail in a lower corner.
Recheck with neighbors
Put two versions among realistic neighboring cards and keep the same order for each round. Check what you notice first without zooming. This is a visual review and can reveal readability issues before you collect audience data.
Mark one fix per surface
For search, the title may need a clearer subject early. For a small sidebar, the crop may need to get tighter. Export the version that handles the most important placements, then inspect the exported copy again.
