CartesianValueSummaryTheme class

Theme defaults for the Cartesian value summary panel.

CartesianValueSummaryStyle overrides resolve against these defaults: an inherited field takes the value defined here, while an explicitly cleared field stays cleared with no fallback to this theme. The fixed overlay and the draggable annotation presentation resolve against the same component, so both stay visually consistent.

The presets keep the panel legible in high contrast, at 200% text scaling, and on dark plot backgrounds; text colors never rely on the panel surface remaining opaque.
