Locked mirror-selfie camera, no zoom

Locked mirror-selfie camera, no zoom.
Preserve subject and phone perfectly.
Animate chosen props (any type) emerging from floor and wall seams, flowing in and stacking to WAIST height only; background fills first, then mid-pile, then subtle out-of-focus foreground edges. Keep torso/face/phone clear.
Maintain ceiling spot highlights and steel reflections; strong contact shadows; objects compress where they touch legs.
Smooth ease-in-out; tiny handheld micro-jitter only.
