Recomputes each promoted layer’s capture rect (inflated by the node’s quantized filter outset — blur reads/writes beyond the border box, and the composite quad, texture allocation, and synthetic-view ortho all derive from this rect), the subtree membership map, and each layer’s content-geometry hash (see fold_member_geometry). Also warns (filterBleed) when a nested filtered layer’s inflated rect escapes its enclosing layer’s capture — v1 clips there, losing part of the bleed. Runs in PostUpdate after bevy_ui layout so ComputedNode / UiGlobalTransform are this frame’s values.
