v4.59.0 — Stockroom Tune-Up

A deep service pass on the machinery that runs the shop and the Circuit. The Parts Counter's price book now covers every aisle — plates, banners, nameplates, walls, and entrances all get proper suggested prices instead of the bargain-bin default, and the Spectraflame Flake finishes are finally recognized as the premium paint they are. The weekly restock now leaves a note on the Dispatch board saying what it did (or why it stood down), and sitewide event theming got a real pre-flight: takeover themes are checked before they save, preview on your own screen first, and can go live with one press. Behind the counter, the season art pipeline was reorganized so future Circuit seasons roll out of the paint booth faster.
