- Segments page: new /segments route with auto-generate (1km splits, turn
detection, hill detection), manual segment creation, per-segment performance
times across matched activities; fixed auth on existing segment endpoints
- YTD distance: new /activities/stats/ytd endpoint; Dashboard replaces
'Total distance' with 'Running this year' + 'Cycling this year'; Activities
page shows YTD stats row
- Weekly chart click: clicking a Dashboard bar navigates to Activities filtered
to that week; Activities reads from/to query params with dismissable chip
- Route matching: add ±2.5% distance gate + 3% relative DTW threshold
(was flat 80m); tighten candidate pre-filter from 80/120% to 95/105%
- Body battery layout: HR chart and body battery now side-by-side at same
height on large screens instead of stacked full-width
- Pace display fix: MetricTimeline clamps GPS speed outliers before computing
Y-axis domain; tick formatter guards against v<=0 or v>25 m/s
