Two blocks, Block \(X\) of mass \(2m\) and Block \(Y\) of mass \(m\), are held at rest on a horizontal frictionless surface with an ideal compressed spring between them. When the system is released from rest, the spring pushes the blocks apart until it fully decompresses and detaches from both blocks. Block \(Y\) slides to the right and ascends a frictionless curved ramp, reaching a maximum vertical height \(H\). In terms of \(H\), what is the maximum vertical height reached by Block \(X\) as it ascends an identical frictionless curved ramp to the left?
