/*
    The Gantt chart. Global rather than scoped because the chart lives in this shared library and
    is drawn by pages in both tiers; the `gantt-` prefix keeps it out of everything else's way.

    Bars are positioned in pixels by the component — it owns the calendar maths. This file owns
    everything else.
