配方
Studio-to-hero transformation, 1:1. Open on a battered white sneaker caked in dried mud under harsh flat overcast — scuffed, gray, joyless. [0-2s] locked low-angle hero shot, dust motes drifting, fully desaturated. [2-3s] a passing cloth swipes the lens for a fast whip-pan wipe transition, motion-blur smearing the frame. [3-6s] the wipe clears to reveal the same {产品名} silhouette spotless and crisp — knit texture sharp, midsole bright white, a soft rim light tracing the laces against clean studio key. [6-8s] slow orbit around the heel, micro-reflections gliding across fresh mesh, ground shadow tight and grounded. The shoe keeps identical proportions, logo placement, eyelet count, and lace pattern across both states — no deformation, morphing, or invented detailing. Implied sound: a stiff brush sweep, the clean snap of laces pulled tight.验收
