Calculate astrocartography geometry and optional downloadable maps

Returns MC and IC meridians plus sampled geometric rising and setting curves for 1-10 selected DE440 bodies. Set include_geojson true for a deterministic RFC 7946 FeatureCollection with four ordered features per body. Set include_geojson_seq true for the same ordered features as a deterministic RFC 8142 GeoJSON Text Sequence. Set include_ndjson true for those features as deterministic LF-terminated newline-delimited JSON records. Set include_topojson true for deterministic unquantized TopoJSON with a named GeometryCollection and central arc inventory. Set include_kml true for a deterministic OGC KML 2.2 artifact with four ordered placemarks per body and integrity metadata. Set include_gpx true for a deterministic GPX 1.1 artifact with four ordered tracks per body and preserved date-line track segments. Set include_csv true for deterministic RFC 4180 rows that preserve every authoritative geometry point and date-line segment. Set include_wkt true for one deterministic WKT GEOMETRYCOLLECTION with fixed geometry ordering and preserved date-line segments. Set include_wkb true for the same collection as deterministic OGC WKB 1.x little-endian binary. Set include_gml true for deterministic GML 3.2 in a CRS84 MultiGeometry with preserved date-line curves. Set include_svg true for a deterministic 1200x800 coordinate-grid map and include_png true for its PNG derivative. Light, dark and monochrome themes are supported. Curves use a fixed two-degree calculation grid from -88 through +88 and split at the date line; the visual renderer connects fixed four-degree display samples. Set basemap natural-earth-110m with include_svg true for bundled public-domain coastline v4.1.0 and pinned provenance; default coordinate-grid-only is unchanged. No runtime map fetches, arbitrary sampling, map tiles, political boundaries, refraction, terrain, interpretation, ranking or recommended places are provided. One standard quota unit per admitted request, including any export; failed or timed-out admitted attempts are not refunded. Historical mode uses an explicit BCE/CE date object and UT1 conventions. Its response is the versioned historical envelope, not the modern UTC envelope. Read result for calculation fields and metadata for limits and uncertainty.
