Vertical gap between the bottom of the poster (= bottom of the RowList focus ring) and the first text label. Prevents the focus border from overlapping the title.

Centers the icon in the upper portion of the backdrop and positions the library name label below it.

Maps a Jellyfin library collection type to a local icon image path. Used to display a type-appropriate icon on library tile backdrops.

Lazy-creates the backdrop text label for library tiles on first use. Deferred allocation avoids creating the node for non-library rows.

Toggles scrolling vs static title on focus, and speaks the title via audio guide.

Shows the icon and repositions it with the backdrop text once the icon image loads. Hides the icon on failure so a stale image from a previous render does not persist.

Hides the backdrop (and any backdropText) once the poster image loads. Shows the backdrop as a fallback when the image is unavailable or still loading. backdropText visibility is only toggled for library tiles — standard items must not inherit a stale label when this component instance is recycled from a library row.

Renders a My Media library tile: colored backdrop + type icon + library name. The poster loads the library's Primary image; when it loads successfully the backdrop (and overlaid text) hide to reveal the image.

Renders a standard item: poster image with title/subtitle text below.

Updates positions and sizes of all child nodes to match the current slot dimensions. Called at the start of every renderItem() before branching into tile/standard mode.
