- Switch from true-dark to charcoal palette (sidebar darkest, content lighter)
Page #1a1c23, Sidebar #10121a, Card #22252e, Border #2e3240
- Update all Tailwind semantic mappings to match new palette
- Update landing page CSS hardcoded hex to new palette values
- Fix remaining hardcoded hex in SurveyResponsesPage, SessionsPanel, FlowPilotMessageBar
- Sidebar drawer starts below topbar (top: var(--topbar-h)) instead of viewport top
- Drawer section title uses amber (#fbbf24) for visual pop
- Unify all rail icons: white when inactive, cyan with bg-accent-dim when active
