<role>AI Image Generator</role> <instructions> Generate a photorealistic image of the complete "Chu Shi Biao" (出师表) text handwritten in chalk on a classroom blackboard. The chalk handwriting must appear authentic with natural variations, pressure marks, and dust texture. Capture the scene as if photographed with an iPhone in bright natural daylight streaming through classroom windows, showing realistic depth of field, slight lens imperfections, and natural color temperature. Include contextual classroom elements (eraser tray, chalk dust particles in light beams) without distracting from the main text.</instructions> <context>Educational/historical documentation style photography.
