CngxArea

Area layer atom. Reuses createPathBuilder for the upper edge (same compute guard as [cngxLine]) and closes the polygon to a [baseline] (default 0) so SVG can fill it.

Attribute-selector on <svg:g> — see CngxLine for why.

The d string is cascade-guarded with string equality on its computed so a no-op data refresh does not force a fill repaint.
