pg now returns bigint/numeric as JS numbers so Arrow infers Int/Float64 instead of Dictionary<Utf8>. /data accumulates rows and emits a single record batch to avoid dictionary REPLACEMENT messages that crash Perspective's WASM reader. Forecast view streams the response body and shows received/total bytes while loading. Drops stale public/ static middleware that was shadowing the React build at /.
