Problem: ComposeCookBook has animation demos, but no showcase for modern shared element transitions.
Proposed solution: Add a demo using SharedTransitionLayout + sharedBounds for list/detail or card/filter transitions.
Why now: Official compose-samples uses this in Jetsnack FilterScreen.kt; ComposeCookBook currently has no SharedTransitionLayout or sharedBounds usage.
