X Boost Post Feature Intro in Sheet Animation

The interaction begins with a scrollable pricing tier picker inside a bottom sheet. Once a tier is selected, the picker collapses into a single row, revealing a 'Boost Post' button. Tapping this button triggers a transition where the picker elements fade out, and a preview of the user's post animates in with staggered scaling. A 'Boosted' badge slides into view, and the post's engagement metrics (likes, reposts, views) rapidly count up, simulating the real-time effect of the boost.
