ImageFit = "icon" | "cover" | "contain" | "frame"

How an imagePath picture sits on the node's shape.

'icon' — small picture centred on the shape (~1.2× size); the legacy default look.
'cover' — picture fills the shape's box (2× size), cropped to preserve aspect ratio.
'contain' — whole picture fits inside the shape's box (2× size), letterboxed with the shape color.
'frame' — the node becomes a rectangle sized to the picture's own aspect ratio (longest side = 2× size), so the stroke hugs it: whole picture, no crop, no letterbox bars. The requested shape is ignored (always a rectangle) since the picture is the node.
