  S7: Verify Highcharts built-in label collision avoidance; if insufficient, build measured-bbox
  layout
type: task
status: completed
description: >-
  FIRST verify whether Highcharts dataLabels.allowOverlap:false plus existing outlier-only filtering
  is sufficient. ONLY IF NOT, implement two-pass measured-bbox layout in
  scatter-plot-label-layout.js: render with allowOverlap:true, capture bboxes via chart callback,
  greedy non-overlap pass. Fall back to existing heuristic on failure. See parent plan.
