The single-waterline trace-in was invisible with sparse data (2 points draw in one step). Replace it with a per-series waterline: each station's line now traces left->right on first appearance, series revealed 0.18s apart in a cascade so the draw is clearly visible. Newly-added favourites get a full reveal immediately on reload; Reduce Motion still jump-cuts. Range/mode morphs and numeric headline transition unchanged.
