tests/nested-both-headers.nowline
// Tall-roadmap readability fixture — exercises the opt-in
// `timeline-position:both` mirrored bottom date strip and the
// `minor-grid:true` per-tick faint grid. Several swimlanes keep
// the canvas tall so scrolling the rendered SVG hides the top
// strip; the mirrored bottom strip keeps date context visible.
