They represent separate source-pin connection objects. The positive copper areas overlap and form one continuous region in fabricated copper; the outer shape is a footprint pad, not a board pour. The inner pads have no separate F.Mask or F.Paste layers. The containing custom pad carries the mask opening; paste apertures are separately defined.++The hero currently outlines each pad object, including these internal boundaries, rather than only the combined copper perimeter. This is a visualization ambiguity, not a cutout instruction. Copper, mask and paste need distinct labelled views. The footprint came from the ESC source board; manufacturer land-pattern and assembly qualification is not established merely by this explanation or by a successful 3D render.++ ## Pin-1 visibility correction — 2026-09-17  The current main STEP and hero GLB include a high-contrast pin-1 orientation dot as well as the MPN. The earlier independent nominal model omitted this dot; the footprint previously relied on a subtle asymmetric outline. The footprint now includes a separate silk dot outside the pin-1 corner. Original variants remain available as history.
