+## Title
+
+fix: preserve timer state across orientation changes (#74)
+
+## Description
+
+This PR resolves the issue where the meditation session timer would reset or
+stop when the device orientation changed
+(e.g., rotating a phone or resizing a window).
+
+### Key Fixes
+
+* **State Preservation**: Added a `GlobalKey` to the
+  `AppCircularCountDownTimer` in `lib/widgets/timer.dart`.
+  This ensures that the widget's internal state
+  (which tracks the active timer's progress) is preserved when
+  Flutter moves the widget between different positions in the tree
+  during an orientation change (Portrait Column vs Landscape Row).
+
+* **Sub-Widget Stability**: Added a stable `ValueKey` to the internal
+  `CircularCountDownTimer` in
+  `lib/widgets/app_circular_countdown_timer.dart` to provide
+  additional stability during rebuilds.
+
+* **Consistent UI**: The `TimerState` now correctly persists its local
+  configurations (duration, guided mode, etc.) throughout the
+  app's lifecycle during layout shifts.
+
+## Related Issues

+Fixes #74
+
+## Type of Change
+
+* [x] Bug fix (non-breaking change which fixes an issue)
+* [ ] New feature (non-breaking change which adds functionality)
+* [ ] Breaking change (fix or feature that would cause
+  existing functionality to not work as expected)
+* [ ] This change requires a documentation update
+
+## How To Test
+
+1. Start an InnerPod session.
+
+2. Rotate your device (or resize the window if on desktop/web) to switch
+   between portrait and landscape modes.
+
+3. Observe that the timer continues its countdown from the current point
+   without resetting to the initial duration or stopping.
