TaroMind AI Birth Card Calculator

I built this browser-based tarot birth card calculator to make the calculation inspectable. It shows the MM + DD + CC + YY arithmetic, explains the reduction steps, and links the resulting Major Arcana cards to their meanings. The date stays in the browser and no sign-in or AI request is needed. The implementation is a small deterministic TypeScript utility inside a Next.js app, rather than an AI-generated calculation. It is intended as an educational reflection prompt, not a personality test or a prediction. A design choice worth sharing: explain the method next to the result, so someone can reproduce it by hand and understand why different calculators may disagree.
