### New Features
* Added Shulker Box delivery support — matching items inside shulkers count toward order fulfillment.
* Shulker contents are scanned from shulkers placed in the delivery GUI and from shulkers anywhere in the seller's inventory.
* Added `items.yml` for configuring allowed order materials separately from `config.yml`.
* Added Modrinth update check on plugin startup (`update-check.enabled` in `config.yml`).
* Added `donutorders` as a command alias for `/orders`.
### Improvements
* Allowed materials are validated server-side when creating orders (prevents GUI bypass).
* Invalid material names in `items.yml` log warnings instead of crashing the plugin.
* `/orders admin reload` now reloads `config.yml`, `messages.yml`, and `items.yml`.
