 *   - rateLimitWaitMs: read X-RateLimit-Reset header and return ms to wait
 *   - sleep:        small helper
 *   - pLimit:       tiny concurrency cap (no external deps)
 *
 * These exist so a single transient 5xx doesn't fail an entire daily
 * refresh, and so we can run the per-app loop with bounded concurrency
 * instead of one round-trip at a time.
