Since the palette update, four of the eight graph lanes sit in one hue band: lane 0 --link #404ddd, lane 1 --closed #8957e5, lane 5 --i-blue #1a85d4 and lane 7 --i-indigo #693acf (GRAPH_LANE_VARS in gs-render.js). Lane 0 was teal before. Dark theme is worse: --link resolves to #9483ed while --closed stays #8957e5, so the two most-used adjacent lanes are nearly the same violet. Reorder or replace the lane tokens so neighboring lanes never share a hue band, in both themes.

Fixed on main by #commit:b52cdd047a69: the lane order alternates warm and cool tokens (warn, i-blue, open, link, danger, i-cyan, i-orange, closed) so neighbors never share a hue band, wrap included. Validated computationally in both themes: light passes every check including CVD separation; dark passes CVD, normal-vision and contrast. The browser battery is all green, the style baselines and goldens are unchanged (no captured route shows the graph), and the review found no issues.
