An HTML label layer that tracks 3D positions, via three's CSS2DRenderer. Labels are real
DOM nodes (crisp text, CSS-stylable) positioned each frame to follow points in the scene — the
foundation for measurement readouts, dimension annotations, and point tags.
The CSS2D renderer draws into its own absolutely-positioned DOM overlay stacked on top of the
WebGL canvas (pointer-events disabled so it never steals clicks from the viewer). The viewer owns
one of these; features like the measure tool add/remove labels through it.
