Family Sequence of Sheets Vary in Height Interaction

In this multi-step setup flow, the bottom sheet container dynamically adjusts its height to perfectly fit each step's content. As the user taps 'Continue' or selects options, the sheet morphs with a springy, fluid animation. The internal content crossfades and shifts vertically, creating a seamless, single-container feel rather than abrupt page transitions. This is especially prominent when transitioning from the compact preset amount selector to the taller custom keypad input, and finally to the detailed review and gas estimation sheets.
