Final answer:
The provided information is about the symbolism of the Mississippi flag, not Missouri's. The central design of the Mississippi flag reflects the state's history and its values, focusing on reintegration and honoring indigenous peoples.
Step-by-step explanation:
The question 'Why is the coat of arms centered on the Missouri Flag?' appears to be based on a misunderstanding. The provided text references the design process and symbolism behind the Mississippi state flag, not Missouri's. Therefore, it is not accurate to provide an answer for Missouri's flag based on this information. However, discussing the symbolism of the current Mississippi flag, which features a central magnolia and stars, the design purposefully reflects the state’s history and values, symbolizing the state's reintegration into the Union and honoring indigenous peoples, with no explicit reference to its history of enslavement and racism.
