 - Serves JSON API routes and the built frontend from `web/dist`.
 - Queries and aggregates station observations in PostgreSQL.

+- Contains ingestion/parsing code for LVGMC station and forecast data, both the private FTP feed (`fetch.lvgmc.FetchService`) and, as of 2026-08-23, a free/keyless open-data alternative (`fetch.lvgmc.OpenDataStationService`) that pivots LVĢMC's public `data.gov.lv` station-observation feed into the same `weather` table — the two run in parallel during evaluation; see `docs/UPDATE_ROADMAP.md` Phase 7.
 - Fetches LVĢMC open hydrometeorological-warning metadata and polygon coordinates on request, with a 5-minute in-memory cache and stale-data fallback if the upstream call fails.
 - Contains HARMONIE discovery, download, GRIB parsing, and rendering support.
 - Starts scheduled ingestion/cleanup tasks unless `ENABLE_SCHEDULED_JOBS=false`.
