 # Gameplay Layout Improvements - Enhancement Report
 
 ## Overview
+
 Enhanced the gameplay state visual layout by repositioning the next piece preview higher above the main grid and adding subtle grid lines to improve gameplay visibility.
 
 ## Changes Made
 
 ### 1. Next Piece Preview Repositioning
+
 **Problem**: The next piece preview was positioned too close to the main game grid, causing visual overlap and crowded appearance.
 
 **Solution**:
+
 ```cpp
 // BEFORE: Limited space for next piece
 const float NEXT_PIECE_HEIGHT = 80.0f; // Space reserved for next piece preview

+### Result
+
 - ✅ **50% more space** above the main grid (80px → 120px)
 - ✅ **Clear separation** between next piece and main game area
 - ✅ **Better visual hierarchy** in the gameplay layout
 
 ### 2. Main Grid Visual Enhancement
+
 **Problem**: The main game grid lacked visual cell boundaries, making it difficult to precisely judge piece placement.
 
 **Solution**: Added subtle grid lines to show cell boundaries
+
 ```cpp
 // Draw grid lines (subtle lines to show cell boundaries)
 SDL_SetRenderDrawColor(renderer, 40, 45, 60, 255); // Slightly lighter than background
