*   Refactored `UnifiedPlayerSheet` to use `Modifier.offset` instead of `Modifier.height` for expansion, eliminating layout thrashing.
*   Updated `FullPlayerContent` to accept expansion fraction as a provider lambda `() -> Float` to prevent expensive recompositions during drag.
*   Moved staggered animations (alpha, translation) into `Modifier.graphicsLayer`.
*   Optimized shadow rendering by using `RoundedCornerShape` for the shadow layer while keeping `AbsoluteSmoothCornerShape` for the visible background.
*   Implemented `zIndex` and off-screen offset logic to ensure correct interactivity of MiniPlayer and underlying content.
*   Fixed compilation issues related to `TopAppBar` and `Scaffold` parameter usage.

Updates the `MarqueeText` composable in `LibraryScreen.kt` to align with a recent API change.

- The `expansionFraction` parameter, which previously accepted a `Float`, is now changed to `expansionFractionProvider`, which accepts a lambda `() -> Float`.
- The implementation is updated from `expansionFraction = 1f` to `expansionFractionProvider = { 1f }` to match the new function signature.
