1. **rightl0 (L-shaped piece)**   - **Shape:** L-shaped, composed of three connected squares.   - **Position:** Occupies positions f2-1f, f3-1f, and f3-2f.   - **Size:** Spans vertically (2 height) and horizontally (2 width) in an L-shape.   - **Status:** Color is blue; outer edges are bold.   - **Text Identifiers:** "rightl0" positioned in each sub-square.2. **rightl1 (L-shaped piece)**   - **Shape:** L-shaped, composed of three connected squares.   - **Position:** Occupies positions f0-1f, f1-1f, and f1-2f.   - **Size:** Spans vertically (2 height) and horizontally (2 width) in an L-shape.   - **Status:** Color is green; outer edges are bold.   - **Text Identifiers:** "rightl1" positioned in each sub-square.3. **square0 (One-square piece)**   - **Shape:** Single square.   - **Position:** Occupies position f1-0f.   - **Size:** Single unit.   - **Status:** Color is red; all edges are bold.   - **Text Identifiers:** "square0" positioned slightly higher in the square.4. **square1 (One-square piece)**   - **Shape:** Single square.   - **Position:** Occupies position f2-0f.   - **Size:** Single unit.   - **Status:** Color is yellow; all edges are bold.   - **Text Identifiers:** "square1" positioned slightly higher in the square.5. **Grid Cells (Unoccupied)**   - **Shape:** Rectangular grid composed of individual squares.   - **Position:** Covers positions f0-0f, f0-2f, f0-3f, f1-3f, f2-2f, f2-3f, f3-0f, f3-3f, f4-0f, f4-1f, f4-2f, f4-3f, f5-0f, f5-1f, f5-2f, f5-3f.   - **Size:** Single unit for each grid cell.   - **Status:** Clear (no color).   - **Text Identifiers:** Each position marked with text (e.g., "f0-0f") located at the center of the square and labeled as "clear".Overall summary:- The Tetris grid is a 6-row by 4-column structure, with specific pieces occupying designated squares. Each piece is given a unique color for clarity, and the outer edges of each piece are bolded to distinguish them from the inner lines of the grid. Position identifiers and text are carefully positioned to ensure clear visibility and avoid overlap.
