- Highlight the vertical rail on conversations open in tabs with a darker primary tint and bleed 1px at both ends to stay continuous across cards
- Add emphasized state to SidebarStatusIcon mirroring the rail, deepening color when the conversation is open in a tab
- Redesign done icon as outlined circle + check, unify all status icons to sidebar-primary with consistent 0.75rem size and sidebar-tinted backdrop so they mask the rail
