TopAppBarTileSchema

Renders a Material 3 top app bar. barStyle picks the composable: TopAppBarStyle.DEFAULT → TopAppBar, TopAppBarStyle.CENTER_ALIGNED → CenterAlignedTopAppBar, TopAppBarStyle.MEDIUM → MediumTopAppBar, TopAppBarStyle.LARGE → LargeTopAppBar.

Slots: title is rendered in the title slot (any tile, most often a SimpleText), navigationIcon in the leading slot, and actions in the trailing slot, laid out inside a RowScope. Both navigationIcon and actions are optional and render as empty slots when omitted.

Triggers dispatched: none. The bar itself emits no trigger and is not clickable, so any events declared on it are never fired — wire events on the slot tiles (typically IconButtons) instead.

Notes: the bar has no scroll behavior, so the medium and large variants do not collapse as the content scrolls.
