Shop Atmosphere

“The workshop smells of burnt brass and lemon oil. Tessa hums old forge hymns while she works, and she will not stand for customers touching lenses without gloves. She marks salvaged parts with a tiny cog stamp and gives a 10% discount to anyone who brings in usable salvage. A sleepy clockwork moth nestles in the rafters and occasionally drops tiny brass feathers on the counter.”
