Origin
The parts left. The high window stayed.
In 2019 the cage emptied. The window was the expensive part. Ione started drawing rails for people tired of buying soles in clean warehouses.
Cedar Rapids is not a resort lab. It is a mill street with dust that steepens shoulders. The ledger exists because catalog slots kept failing that dust.
Mail still arrives for the parts company. We return it. The overlay only answers rail questions.
