    The flickering neon light of the "24-Hour Tech & Repair" sign hummed a low, buzzing B-flat that matched the headache throbbing in Elias’s temples. On his workbench sat a pre-war industrial controller—the kind of hardware that shouldn't exist anymore, let alone need a firmware update. Cause: Your browser or ISP cached a broken partial download

    "You find it?" a voice rasped from the shadows of the shop. It was Miller, a man whose paycheck depended on that controller running the city’s water filtration grid.
