CngxBand

Band reference atom. Renders a <rect> across a vertical Y-range (from..to) spanning the chart's full width. Use to highlight a value range (e.g. "good zone", "watch zone") behind primary layers.

Default opacity is low (var(--cngx-band-opacity, 0.12)) so the band sits behind line / area / bar layers without dominating.

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