Updated status badges, status values, and skip links in index.html, dashboard/index.html, and scripts/web_dashboard.py to use darker shades (Emerald 700, Amber 700, Indigo 700) instead of lighter ones (Emerald 500, Amber 500, Indigo 400). This ensures text meets WCAG AA contrast ratio requirements (4.5:1) against white backgrounds. Also updated the .jules/palette.md journal.
