This is the staging interposer-hardware KiCad project renamed to
interposer-hardware-bottom during the 2026-08-25 migration.
The board starts with the source geometry and circuitry unchanged. The top board was created as an independent duplicate at the same migration point so the two designs can now evolve separately.
The whole display-module mock is referenced from the shared 3D model library.
The current board also contains parked component footprints outside
Edge.Cuts; use a board-only STEP export when a mechanically honest bottom
board snapshot is needed.
