Gold #FFD700 has 1.4:1 contrast ratio on white — barely visible.
Replace with dark amber palette (#8B6508 primary, #7A5800 links)
that passes WCAG AA (5.3:1 and 6.5:1 respectively).
Changes:
- :root primary palette → dark amber tones for light mode
- Explicit light mode link colors (#7A5800 / #5A4100 hover)
- Light mode sidebar active state with amber accent
- Light mode table header/border styling
- Footer hover color split by theme (gold for dark, amber for light)
Dark mode is completely unchanged.
