BaZi Chart

Calculate one static natal chart, write bazi_<name>.json and bazi_<name>.md, then hand the verified JSON to bazi-reading automatically. The artifacts contain calculation data only; never interpret the chart here.

Route before calculating

• If the user supplied two people and wants to know whether they match, route to bazi-compatibility.
• If the user supplied an existing chart and wants meaning, route to bazi-reading without recalculating.
• If they ask for Da Yun, annual luck, event dates, or forecasts, state that this first release is natal-only and do not improvise those calculations.
