+# 05. Design Layered Navigation UI System
+
+meta:
+  id: podtui-navigation-theming-improvements-05
+  feature: podtui-navigation-theming-improvements
+  priority: P2
+  depends_on: [podtui-navigation-theming-improvements-02, podtui-navigation-theming-improvements-03, podtui-navigation-theming-improvements-04]
+  tags: [design, navigation, ui]
+
+objective:
+- Design the layered navigation UI based on user requirements
+- Create visual design for layer separation and active states
+- Define how layers should be displayed and navigated
+
+deliverables:
+- Navigation design document
+- Layer visualization mockups
+- Clear specifications for layer colors and borders
+- Implementation plan for layered navigation
+
+steps:
+- Review user requirements for navigation (clear layer separation, bg colors, left/right navigation, enter/escape controls)
+- Analyze current layerDepth signal implementation
+- Design layer separation mechanism (borders, backgrounds, spacing)
+- Define active layer visual state (bg color, borders, indicators)
+- Design navigation controls (left/right arrows, enter arrow down, escape arrow up)
+- Create layer visualization showing how multiple layers should work
+- Document layer structure and hierarchy
+- Create implementation plan for Navigation component
+- Define theme colors for layer backgrounds
+
+tests:
+- Unit: None (design task)
+- Integration: None (design task)
+
+acceptance_criteria:
+- Navigation design document is created
+- Layer separation mechanism is clearly specified
+- Active layer visual state is defined
+- Navigation controls are documented
+- Implementation plan is provided
+
+validation:
+- Review design document for clarity
+- Verify it addresses all user requirements
+- Check that design is feasible to implement
+
+notes:
+- Layers should be clearly delineated with visual separation
+- Active layer should have distinct background color
+- Navigation should be intuitive with clear visual feedback
+- Consider terminal width limitations
+- Design should work with existing theme system
