    WaterfallKind: "increase" | "decrease" | "total"

    What a waterfall step does to the running total.

    total marks a step that restates the running total rather than changing it — the opening and closing bars, and any subtotal drawn along the way. Those sit on the baseline instead of floating, and a reader told a subtotal "rose by 950" would be hearing a contribution the chart never made.
