`calculate_birth_chart`Calculate a complete natal chart for “my birth chart”, “tema natale”, “calcola tema natale”: planets, Ascendant, Whole Sign houses, major aspects, uncertainty and one-line meanings with links. Approximate times need a ±15,30,60 or 120 minute window; supports fold choice and historic offset override. Ask for missing birth time and birthplace instead of guessing. If the user does not know the time, explicitly use unknown: no Ascendant or houses, and both Moon signs when applicable. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.
