A Chinese metaphysics web app that translates 2,000+ years of Four Pillars (Bazi) tradition into a modern, interactive experience. Generates natal charts with Heavenly Stems and Earthly Branches, computes Day Master personality profiles and Ten God relationships, maps Luck Pillars across decades, and includes a Date Selection engine powered by the Twelve Day Officers system. All driven by a pure TypeScript calculation engine with zero API dependencies.

// takeaways

Domain-specific calculation engines are best built client-side when data is deterministic and bounded
Dark luxury design direction needs restraint — gold accents work when used sparingly
Building for yourself first produces the most honest product decisions
Solar term accuracy is critical for Bazi and required bundling authoritative lookup data
