+# Sub-Task 3: Header Pause Button Removal (Bug 5)
+
+## Scope
+- **Components affected**:
+  - `components/Header.tsx` (remove pause button from header row)
+  - Potentially header-related styles or layout components
+- **Files potentially affected**:
+  - `components/layout/Header.tsx` if header is nested
+  - Style files (CSS/SCSS/Tailwind) related to header if button styles need cleanup
+
+## Acceptance Criteria
+1. Pause button is completely removed from the header row (verify visually in UI)
+2. No broken layout or spacing issues in header after removal
+3. No references to removed pause button remain in code (check for unused imports/handlers)
+
+## Dependencies
+- None (independent sub-task)
+
+## Estimated Complexity
+- Low (simple component removal)
