- Dark theme: .tabular-cell color was overriding .tabular-row-selected color
due to same specificity and later position. Added !important and combined
selector .tabular-row-selected .tabular-cell to fix.
- Added background-color change for selected rows (both themes)
- Added cursor:pointer on .tabular-row for better UX
- Light theme: added blue-tinted background + darker text for selected rows
