Detailed Description

Context for post-layout callbacks (AddPostLayout).

Fires once per registered element AFTER layout completes and BEFORE rendering starts. Read-only - no drawing primitives.

Use this for state updates that depend on final geometry. For example:

• cache an inner-rect size for use by next frame's UI code,
• compute screen-space endpoints from layout rects for a custom subsystem,
• record a transformed origin for a separate AddCustomDraw to consume.

All rects returned are in LAYOUT space (pre-transform, window-local). The element's contentTransform is exposed verbatim for callers that need to map points themselves.
