Load development analytics — powder charge and seating depth tests

Import velocity data from Garmin Xero C1, Athlon, ShotMarker, or any CSV. ChronoLab auto-parses into series and individual shots, then renders scatter/line graphs with ES, SD, and average overlays. Save graphs with custom titles and export to PNG or PDF.
