Live endpoint: /f/<slug>/<feed-id>.geojson
Returns the current snapshot as a GeoJSON FeatureCollection.
HTTPS only, CORS-open, no query string. The slug is per-feed and stable
across deploys — it's obscurity, not access control, so don't publish
anything here that would matter if the URL leaked.
History query: /q/<slug>
Filtered queries over each feed's curated Parquet history via DuckDB.

|---|---|
bbox | west,south,east,north |

limit | default 1000, hard cap 10000 |

/public-catalog.json lists every listed feed's metadata with
no URLs — safe to link publicly. The private /catalog.json
additionally carries each feed's endpoint URLs.
