Phase Hexwell

Normal drops stop on roofs and charge the capacitor. Phase drops spend that charge to reach the deepest cavity. Clear three bands by coordinating both modes. The capacitor stores at most one charge. Clearing a row does not recharge it: another normal drop does. Phase material can pass through occupied cells but must land in two empty neighbors. Aim and mode changes are free. Undo restores board, charge and mode. No timer.
