the series tooltip dropped the name whenever only one line was drawn, so a dot beside a number was the whole story — unreadable if you can't see the dot's hue. every row is named now. endpoint and status views use Okabe-Ito colors, and status lines also carry a dash pattern per class (solid/dotted/dashed/dash-dot) so 4xx vs 5xx never rides on hue alone.
