/**
 * Generate multi-geometry "+" badge decorations for a feature.
 *
 * Returns one decoration per **logical** part of a multi-geometry (MultiPolygon,
 * MultiLineString, MultiPoint). Parts are counted after running the feature
 * through the same antimeridian seam-merge the render adapters apply
 * (`mergeAntimeridianFeatures`), so a shape split at ±180° per RFC 7946 §3.1.9
 * counts as one part and gets no badge — the badge count always matches what
 * the user visually perceives as separate shapes (SAGA-648). Each badge is
 * placed at the part's representative position (from `extractMultiParts`)
 * using a `"position"` anchor with the pre-resolved coordinate.
 *
 * For MultiPoint features a `pixelOffset` displaces the badge to the
 * top-right edge of the point circle so it does not obscure the fill area.
 *
 * Returns an empty array for single-geometry features or multi-geometries
 * with only one logical part.
