Node.js 18+. Ships ESM and CommonJS with bundled type declarations.

• GoogleTrendsFetcher (exported as Client) — the only class you construct. Every query hangs off it.
• ClientOptions — language, timeout, proxies, and the escape hatches for a custom fetch or renamed RPC ids.
• InterestOverTimeResult — the timeseries model, with toArray(), toCSV(), and export().
• ResponseError / TooManyRequestsError — what a 429 means, and when rotating an exit IP will help.
