Struct ChartComposition 

pub struct ChartComposition {
    pub panels: Vec<PanelSpec>,
    pub splits: Vec<f32>,
    /* private fields */
}

Chart panels and their cumulative height ratios.

Adding an auxiliary panel takes height from the primary; removing one returns its height to the primary. Surviving auxiliary panels retain their ratios, subject to minimum-height normalization. Reordering carries each panel’s ratio with it. Heights are proportional, not pixels.

New auxiliary panels receive up to 15%, reduced to an 8% minimum when space is limited. The primary must retain at least 8%.

Fields

panels: Vec<PanelSpec>

splits: Vec<f32>

Normalized boundaries in ascending order, one fewer than panel count.
