Push the green START domino to begin the chain reaction. Depict the complete domino falling process across the image sequence. The dominos fall in order from left to right. The gray trunk falls first, then splits into the red Branch A (upward) and cyan Branch B (downward). Both branches complete successfully. The final state shows all dominos fallen and tilted right. Only modify what the task requires; keep the background and any other element unchanged. Output one image each time a domino finishes falling: one image per trunk-domino fall, then one image per branch step (A and B fall in lock-step). The last image shows the final state.
