Replace bright white backgrounds with warmer off-white tones to reduce
eye strain while maintaining good contrast and professional appearance.
Changes:
- Update CSS variables with warmer neutral palette (#f5f3f0 page bg,
#faf9f7 surfaces, #f0ede8 muted sections)
- Soften primary blue from #2563eb to #3b6fd4
- Update navbar, cards, tables to use new surface colours
- Update upload area, file lists, and icon backgrounds
- Update flag item backgrounds with softer tints
- Update shared components (VeracityScoreCard, FlagsList)
The new colour scheme uses warm off-white/cream tones that are easier
on the eyes than pure white while maintaining professionalism.
