Shopify product media has to work across network conditions and devices, not just on a fast desktop. For mobile memory, test the first useful frame, interaction readiness, and fallback behavior separately.
For Shopify product media, set a numeric budget before reducing detail. Test at the intended camera distance or device class, and keep the threshold where silhouette, shading, or interaction quality first becomes unacceptable.
Measure decoded texture memory and peak scene cost on a representative phone rather than relying only on download size. Apply this mobile memory guidance to the actual Shopify product media delivery path.
