/* Scenario Demand Forecast - design tokens and layout.
 *
 * Layout is the three-pane arrangement from the spec: scenario rail on the
 * left, the baseline-vs-simulated forecast in the centre, filters on the right.
 * Both rails collapse below 1180px, where a three-column layout stops being
 * readable and starts being three columns of nothing.
 *
 * Colour never carries meaning on its own. Every variance badge pairs a colour
 * with an arrow glyph and a word; every chart series pairs its colour with a
 * distinct dash pattern; every verdict chip is labelled. The palette below is
 * chosen so the whole thing still reads correctly in greyscale.
