 * A Gantt chart: a frozen label column beside a zoomable, horizontally scrollable
 * axis, with tasks in lanes.
 *
 * **Reach for this over `CalendarView` when the ROWS are the subject** — a phase,
 * an owner, a vehicle — and dates are the horizontal axis. A calendar answers
 * "what happens on the 14th"; this answers "what is this team doing".
 *
 * **Lanes** come from `group`, **milestones** render as diamonds, and `progress`
 * fills a portion of the bar. There are deliberately no dependency connectors:
 * lane order and bar position already carry the sequence.
 *
 * Renders at its natural height — wrap in a `ScrollView` for very long lists.
