+# 2024-12-18 16:35:00 - Refactor Game Battlefield Sidebar
+
+## Description
+Refactored the `GameView` sidebar to be graphically and functionally consistent with `DeckBuilderView` and `DraftView`.
+
+## Key Changes
+- **Component**: `GameView.tsx`
+- **Functionality**:
+  - Implemented collapsible sidebar state with persistence (`game_sidebarCollapsed`).
+  - Implemented resizable sidebar width with persistence (`game_sidebarWidth`).
+  - Added transition animations for collapsing/expanding.
+- **Visuals**:
+  - Adopted the "Card Preview" style with a 3D flip effect.
+  - Used `back.jpg` (path `/images/back.jpg`) for the empty/back state.
+  - Moved the resize handle *inside* the sidebar container with consistent styling (floating pill).
+  - Preserved Oracle Text display below the card image (as it is critical for gameplay), styled within the new container.
+
+## Consistent Elements
+- **Icons**: Used `Eye` and `ChevronLeft` from Lucide.
+- **Styling**: `slate-900` backgrounds, glassmorphism borders (`slate-800/50`), shadow effects.
+- **Behavior**: Sidebar width allows dragging between 200px and 600px.
+
+## Status
+- [ ] Verify `back.jpg` exists in the deployed `public/images` folder (currently assumed based on other files).
+- [x] Code refactoring complete.
