Design a chocolate packaging inspired by Marou Chocolate's style

Design a chocolate packaging inspired by Marou Chocolate's style. The packaging should feature traditional Vietnamese cultural elements, such as wave patterns, Dong Son drum motifs, and cacao leaves. Use a mix of elegant gold ink on handmade-style paper with intricate details. The color palette should represent different regions of Vietnam, with each package having its distinct hue to signify the cacao's origin. Ensure the design evokes both sophistication and the artisanal craftsmanship of high-quality, single-origin chocolate, staying true to the essence of Vietnamese culture.
