/**
* Date-grouped timeline strip at the top of the report. Walks every
* date-type field across all stage sections (05), pulls each field's
* most-recent entered date, and plots events into six horizontal swim
* lanes — one per stage. Stage 5's `Date_Opened` gets visual emphasis
* as the journey's anchor at the right end of the time axis. A faint
* "Today" tick anchors the reader if today falls within the range, and
* an adaptive month/year axis runs beneath the lanes. Each dot exposes
* a tooltip on hover or keyboard focus.
