Operator-flagged 2026-06-01: with the failing-sources panel expanded, all rows have the same flat low-opacity background, no visual track from the artist name on the left to the Logs/Retry buttons on the right. Hard to tell which row a button belongs to when scanning down a list of 17. Three pure-CSS changes (no DOM, no logic): - 3px gap between rows (was 2px) — slightly more breathing room - Even rows get a darker surface tint (zebra striping) - Hover paints the whole row in a low-opacity error tint, so moving the cursor toward Logs/Retry lights up the whole horizontal band and the eye traces back to the artist name automatically
