Three improvements to the report's DateTimeline:
1. Tooltips on every dot. Each dot is now a focusable span (tabIndex,
role=img, full aria-label). A small ink-tinted card appears above
the dot on mouse hover or keyboard focus, showing field label,
formatted date, stage rank, and an 'Opened' marker for Date_Opened.
Anchor flips to left/center/right based on the dot's position so
tooltips don't overflow the row at the edges.
2. Plot every date field, including stage 0. The previous version
skipped Stage 0 dates (Internal_Startup_Assessment_Date,
Date_Closed_Folded). Now there are six swim lanes (0-5) instead
of five. Stage 0 gets bg-leaf-200 so the gradient extends one
step lighter.
3. Adaptive month/year x-axis under the lanes. generateAxisTicks
picks a 'nice' interval based on the visible span: 1mo / 2mo /
3mo / 6mo / 1yr / 2yr. January-bordered ticks include the year
so the reader has anchors. Today gets its own labeled clay tick
when it falls in range.
