README.md+5@@ -80,3 +80,8 @@ Data extracted from the manufacturer datasheet, not a distributor listing: The main 3D viewer uses [ina181a2idbvr-hero-mpn.glb](ina181a2idbvr-hero-mpn.glb), derived from the reviewed [ina181a2idbvr-mpn.glb](ina181a2idbvr-mpn.glb). The exact MPN is AI-added identification artwork, not a factory marking. [Marking inputs, fit and licensing](MPN-MARKING.md) and [source provenance](PROVENANCE.md) remain applicable. The hero applies only a 180-degree Z display rotation; no geometry is scaled. Use the original-frame marked STEP/GLB downloads for board assemblies. The rendered package and readable mark were reviewed; that does not establish manufacturer-exact dimensions, polarity, or native-tool qualification. [Binding and file hashes](hero-binding.json).+++## Footprint-aware inspection hero++The current hero adds separate nonphysical reference layers: teal dashed copper boundaries at50% opacity, silkscreen at30% opacity and actual symbol pin names (unique pad numbers when unnamed) at50% opacity. Orbit underneath to compare physical terminals, copper and pin1 marks. Copper outlines are not soldermask/paste. Existing MPN, materials, animations and lights are preserved. These helpers are excluded from board-use STEP/GLB files. [Geometry, mapping and source hashes](ina181a2idbvr-hero-footprint.overlay.json); [pin-map input](hero-pin-map.json). Physical body can occlude seating-plane artwork; inspect the underside or isolate it. Generated display-font contours are not native fab artwork.
