咖啡微距流体转场

@Image 1: Push in rapidly toward the milk foam, cocoa particles, and dark liquid texture on the coffee until particles, bubbles, and ripples fill the frame. Keep the macro photography realistic, with extremely shallow depth of field and fine powder drifting through backlight. Let the surface feel suspended between granular sand and fluid. At the exact moment when the cocoa particles, foam contours, and coffee swirl closely resemble the dune ridges, wind-carved textures, and airborne sand in @Image 2, transition seamlessly into the desert landscape. Continue pushing forward until the full dunes from @Image 2 are revealed. No tearing, black frames, hard cuts, obvious VFX, or compositing seams. Keep it photoreal, quiet, and restrained, as though one granular material naturally expands from the microscopic coffee surface into a vast desert. One continuous shot with no visible edit.
