## 🎬 VIDEO LIBRARY SYSTEMS ANALYSIS

### ✅ **KEEP: Library Video Gallery**

- **Purpose:** Primary media library management interface

### ❌ **REMOVE: Unified Video Gallery**
- **Location:** Line 501 (main game screen)
- **Element ID:** `unified-video-gallery`

  - `loadStandardVideoGallery()` (Line 2356)
  - `loadLargeVideoGallery()` (Line 2367)
- **Status:** ❌ **DUPLICATE** - Overlaps with lib-video-gallery functionality

### ❌ **REMOVE: Dynamic Category Galleries**
- **Location:** Generated by `loadVideoGalleryContent()` (Line 2663)
- **Element IDs:** `${category}-video-gallery` creates:
  - `background-video-gallery`
  - `task-video-gallery`
  - `training-video-gallery`
  - `reward-video-gallery`
  - `punishment-video-gallery`
- **Status:** ❌ **DUPLICATE** - Category filtering can be handled by lib-video-gallery

### ❌ **REMOVE: Support Functions**
- `setupVideoItemHandlers()` (Line 2507)
- Selection/deletion functions (Lines 2901-2991)
- **Status:** ❌ **REDUNDANT** - Functionality duplicated in working system

- **Functions:** Lines 4361-4395
- **Status:** ✅ **WORKING** - Primary image management interface

### ❌ **REMOVE: Task/Consequence Image Galleries**
- **Location:** Lines 310, 330, 334 (main game screen)
- **Element IDs:** 
  - `task-images-gallery` (Line 330)
  - `consequence-images-gallery` (Line 334)
- **Status:** ❌ **DUPLICATE** - Can be consolidated into lib-image-gallery

## 🔊 AUDIO LIBRARY SYSTEMS ANALYSIS

### ✅ **KEEP: Library Audio Gallery**
- **Location:** Line 1500 (`library-audio-content` section)
- **Element ID:** `lib-audio-gallery`
- **Status:** ✅ **PRIMARY** - Main audio management interface

### ❌ **REMOVE: Background/Ambient Audio Galleries**
- **Location:** Lines 389, 409, 413 (main game screen)
- **Element IDs:**
  - `background-audio-gallery` (Line 409)
  - `ambient-audio-gallery` (Line 413)
- **Status:** ❌ **DUPLICATE** - Can be consolidated with category filtering
