Timeline

A chronological view of a versioned series. `source` is the class whose instances are placed on the time axis; `orderBy` is the date/datetime property to sort by (ascending — oldest first). Two render modes are selected by whether `track` + `metricPath` are present. Without them, the band renders the bare sequence — one clickable node per instance showing its order value, useful as a navigation axis. With them, the band renders a multi-series trajectory chart (a confidence "fan chart"): `track` names the property on each instance holding the sub-resources to follow (aligned across versions by their stable resource key), `metricPath` is the `/`-separated path from each tracked sub-resource to the numeric value plotted on the Y axis (0..1), and the optional `hueBy` path supplies a per-series hue so each tracked line is themed. One line per tracked key spans the version sequence, with a legend reporting each series' latest value and its delta from the prior version. Used on a PackageView to show the shape of how a worldview evolved (e.g. every WorldviewThesis confidence across snapshot versions).
