Enum RampHint 

pub enum RampHint {
    Sequential,
    Diverging,
    Banded,
    Categorical {
        items: Vec<CategoryItem>,
    },
}

How a variable’s values are meaningfully mapped to a colour scale (spec §6.1).

The only presentation vocabulary this layer contributes, and it is a shape statement, never a colour: an application chooses palettes, band edges, and legend styling; the engine says only which shape is truthful for the data.

Variants

Sequential

Magnitude on a continuous low→high scale.

Diverging

Signed values around a meaningful zero (e.g. flow direction).

Banded

Values classed into user-configurable threshold bands.

Categorical

A closed set of discrete states, with engine-authored items.

Fields

items: Vec<CategoryItem>
