Function apply_geo_features 

pub fn apply_geo_features(
    layer: &GeoLayer,
    target: &mut impl GeoApplyTarget,
) -> GeoApplyReport

One apply pass over a layer’s features. The model-specific lookups and placements come from the GeoApplyTarget; the feature dispatch, match counting, and substation bookkeeping live here, so the balanced network and the multiconductor glue in powerio-pkg report identically.
