+## Features

+- **Duplicate Prevention**: Uses SHA256 image hashing and a local SQLite database to prevent re-uploading the same item twice.
+- **Race Condition Protection**: Uses asynchronous locking to ensure simultaneous requests for the same image don't trigger multiple uploads.
+- **Discord Notifications**: Sends a rich embed to Discord whenever an asset is successfully uploaded.
+- **Metadata Preservation**: Automatically appends a link to the original Roblox asset in the new asset's description.
