-// Package impltracedetail tests — waterfall
-//
-// # Background
-//
-// The waterfall view renders a trace as a scrollable list of spans in
-// pre-order (parent before children, siblings left-to-right). Because a trace
-// can have thousands of spans, only a window of ~500 is returned per request.
-// The window is centred on the selected span.
-//
-// # Key concepts
-//
-// uncollapsedSpans
-//
-//	The set of span IDs the user has manually expanded in the UI.
-//	Only the direct children of an uncollapsed span are included in the
-//	output; grandchildren stay hidden until their parent is also uncollapsed.
-//	When multiple spans are uncollapsed their children are all visible at once.
-//
-// selectedSpanID
-//
-//	The span currently focused — set when the user clicks a span in the
-//	waterfall or selects one from the flamegraph.  The output window is always
-//	centred on this span.  The path from the trace root down to the selected
-//	span is automatically uncollapsed so ancestors are visible even if they are
-//	not in uncollapsedSpans.
-//
-//
-// traceRoots
-//
-//	Root spans of the trace — spans with no parent in the current dataset.
-//	Normally one, but multiple roots are common when upstream services are
-//	not instrumented or their spans were not sampled/exported.
