A toaster rests on the kitchen counter, a familiar appliance for morning routines. You drop slices of bread into the slots and press the lever down. The bread lowers smoothly into place, and the heating elements activate, warming the bread from both sides in a steady process.
The bread remains hidden below the top edge, enclosed as it changes color from pale to golden. The toaster holds this state while the warmth builds.
The threshold arrives precisely when the release mechanism triggers. The bread carrier springs upward, lifting the toast visibly above the slots.
Before this instant, the bread stayed down and continued heating. Right after, the toast stands raised and exposed, with the heating cycle ended. The toaster shifts from active warming to idle completion.
This marks the line crossed: the toaster no longer toasts; it has delivered the bread ready for the next step.
