• No more pykrx dependency for core functionality

• Lookup KOSPI/KOSDAQ ticker symbols and names
• Retrieve OHLCV (Open/High/Low/Close/Volume) data for stocks
• Retrieve market capitalization data
• Retrieve fundamental data (PER/PBR/Dividend Yield)
• Retrieve trading volume by investor type (institutional, foreign, individual)
• Retrieve index OHLCV data (KOSPI, KOSDAQ indices)

• Python 3.10+
• Kakao account (2FA must be disabled)
• Playwright Chromium browser
