vitest.config.ts

// Pin the timezone before anything reads the clock. One golden-master value (a legacy
// loan's settlement row whose `created` falls back to tstamp(), which parses in local
// time) is timezone-sensitive; the golden fixture is captured under UTC (see
// scripts/capture-golden.mjs, run with TZ=UTC), so the tests must run under UTC too to be
// reproducible on any machine / CI. Everything else is timezone-independent.
process.env.TZ = 'UTC'

import { defineConfig } from 'vitest/config'

// Domain tests are pure TS and run in Node, which provides WebCrypto (crypto.subtle),
// TextEncoder/TextDecoder and btoa/atob natively — no jsdom needed for the modules
// themselves. jsdom is installed for the throwaway golden-master capture harness
// (scripts/capture-golden.mjs), which has to run the DOM-coupled oracle script.
