/**
 * tests/3 — Deploy-to-clean-account smoke test.
 *
 * Asserts that a clean `wrangler deploy` of this Worker into an empty account
 * completes in under 4 seconds (Spin's MVP target). This test is gated on
 * CLOUDFLARE_API_TOKEN + CLOUDFLARE_ACCOUNT_ID being set in the environment;
 * skipped in normal CI runs.
 *
 * Run with:
 *   CLOUDFLARE_API_TOKEN=... CLOUDFLARE_ACCOUNT_ID=... \
 *     npx vitest run test/deploy.test.ts
