   Right-Rail Card Layout Contract
   ===========================
   
   All right-rail cards should follow this pattern:
   - Use flex layout to fill available space
   - Header sections are fixed (flex: 0 0 auto)
   - Content sections fill remaining space (flex: 1 1 auto) and scroll naturally
   - No hard-coded max-height constraints on content areas
   
   This ensures consistent, predictable scroll behavior across all tabs.
