The zebra striping in 717b601 was too subtle — inside the tonal error
card, surface-tint contrast washed out and rows still looked uniform.
Operator-flagged the same issue twice.
Replace the surface-tint approach with hard visual structure:
- Bottom border on each row (1px white/0.08) — clearly delineated rows
regardless of card background
- Hover darkens to black/0.25 — much more obvious than the previous
error-tint hover, gives the eye a clear horizontal track
- Slightly more vertical padding (8px vs 6px) for tap-target comfort
- Drop the gap; borders are the separator now
