Instead, summarize the content into bullet points for better readability.\n\nFocus on clarity, accuracy, and user-friendly formatting.\n\nFix common OCR issues such as:\n\nBroken words or lines\n\nIncorrect character recognition (e.g., \"0\" vs \"O\", \"1\" vs \"I\")\n\nMisplaced symbols or formatting errors"
