Grid Calibration

I located a stack of four wooden beverage coasters on the table surface. The circular cork center provided sufficient traction. Using the edge of my foot, I pushed the top coaster outward until its rim aligned precisely with the table's beveled bevel. Next, I took two metallic paperclips from an open dish nearby. I linked them at right angles, testing the pivot resistance between the wire loops. When balanced across the rim of the top coaster, the counterweight held firm without sliding. The structure is stable. Spatial margins are verified.
