Orders API (demo)

A tiny Express service used in Aulay demo and tutorial recordings. In-memory store seeded with three orders on boot; no database.

pnpm install
pnpm dev        # http://localhost:4000
pnpm test       # vitest — one test fails on purpose (see below)

Routes: GET /health, GET /orders, GET /orders/:id, POST /orders ({ customer, items: [{ sku, qty, unitCents }] }).

totals include tax fails until withTotals in src/orders.js adds taxCents to totalCents. The "fix the failing test" tutorial asks an agent to make exactly that change.
