/**
 * Shared helpers for Phase 0 smoke scripts.
 *
 * Each smoke script imports these to:
 *  - Print structured OK/FAIL lines.
 *  - Hit the local dev server (assumed running on http://localhost:3005).
 *  - Bail with a non-zero exit code on failure so CI can chain them.
 *
 * Side effect: populates the env vars src/lib/env.ts requires (P0-8 now
 * fails fast on missing secrets). Smoke scripts that import library code
 * transitively load env.ts; without these placeholders they'd never run
 * standalone.
