Use CardDefaults.cardElevation() with default=2dp, pressed=6dp,
hovered=4dp on both Attribute and Talent cards. Switch from
Modifier.clickable to Card(onClick=...) for proper Material 3
interaction ripple and pressed elevation animation. Extract card
content into private composable functions to avoid duplication
between onClick and non-onClick card variants.
