Generic bounding-box query filtered by a single OSM tag

Return OpenStreetMap nodes, ways, and relations inside a bounding box that match a single tag filter (tag_key=tag_value). Bounding box area is capped at 1 square degree (~110 km x 110 km at the equator) to stay within Overpass resource budgets. The tag_key is restricted to a curated allowlist of top-level OSM keys; tag_value must match [A-Za-z0-9_-]{1,64}. Data is (C) OpenStreetMap contributors (ODbL 1.0) - attribution is required on any surface that renders this data.
