Snack Shift Duo

Builder clears a row to bake a snack; runner catches it within three actions. Move the runner toward the forecast lane before baking. Roles switch freely. In builder mode tap a column then drop. In runner mode tap a neighboring lane. A snack expires after three non-catching actions. The team has eight actions of energy per snack. Undo restores both roles, timer and board. No real-time countdown.
