Keep the product identical in every AI shot

AI video models redraw the product in every frame. With one photo they guess the hidden sides, and long, soft or printed products drift: wedges turn into blocks, labels melt, cans invent a back. This skill locks the product before any clip is generated and checks every clip after.

Generation runs on varg: REST https://api.varg.ai/v2 (the varg-ai skill) or the MCP server https://mcp.varg.ai/mcp.

1. Write the lock sheet (one per product)

PRODUCT: car seat gap filler, single piece
FIXED GEOMETRY: long thin wedge, ~50 cm long, ~4 cm wide at the top, tapering; seatbelt slot near one end
FIXED SURFACE: black leather-like cover, contrast stitching along the top edge, no logo
ALLOWED MOTION: held, slid into a gap, objects dropped on top; never bent, squeezed or rotated fast
NEVER: boxy, shorter, glossy, another color, a second slot

Separate geometry, surface and motion; never mix an old and a new label in the references (seedance.tv).

2. Build the reference pack
