 * Rewritten upstream (observed 2026-10-10) to return usage analytics
 * (`{range, totals:{usage_usd, request_count, …}, buckets}`); the accepted
 * ranges are 24h / 7d / 30d. We request the 30d rolling window — the closest
 * match to a credit plan's monthly billing period, and the numerator for the
 * derived monthly percent. Auth is a plain Bearer API key (docs.ollama.com).
 * No rate-limit headers exist on any Ollama endpoint, so the body is the only
 * data source.
