Start from the supplied illustrated first frame. Locked side camera. The already leaning left tile continues to fall toward the second tile. It visibly touches the second tile before that tile begins its main fall. Repeat this contact-led order from the second to the third, then the fourth. Keep the same four rigid tiles and the fixed horizontal surface. Do not start distant tiles at the same time, stretch a tile across a gap, add a fifth tile or cut away from a contact. End after the fourth tile falls, with all four original tiles resting in a readable arrangement, then hold. This is one small visual cascade, not a calibrated impact simulation.
