spin-life

A "birth lottery" game (clone + extension of spinyour.life). Spin to be born into a random real-world life, weighted by real demographic data — with a social-mobility layer that turns each roll into a life story.

Live (phone-friendly): https://lazyreflect.github.io/spin-life/ — auto-deploys on push to main.

Stack: Vite + React + TypeScript, client-only (no backend), state in localStorage.

• DESIGN.md — full design doc, calibrated math model, open decisions.
• data/countries.json — 241-country dataset (births, net worth, Gini, height, IQ, life exp).
• data/model-params.json — calibrated trait-model parameters.
• data/names.json — 36 culture-cluster name lists. data/careers.json — career catalog.
• sim/simulate.mjs — validates the model against target correlations.
• sim/cards.js — prints sample life-cards using the shared model.
• src/model/*.js — the model, shared by the sim and the app.
