"Design a simple and minimalist icon of a wheelbarrow to be used as a resource in a board game set in the medieval era. The wheelbarrow should have a clean and straightforward design, resembling a classic medieval wheelbarrow with a wooden tray, a single wheel, and two handles. Keep the design minimalist and easy to recognize, evoking the rustic charm of the medieval period. Avoid intricate details or embellishments. The icon should be suitable for printing on cards and game boards, providing a clear representation of the wheelbarrow as a resource within the medieval context."
