I want to know the answer to the following question:
What was the initial difference between majuscule and minuscule letters?
All the background I'm provided with is that "Both majuscule and minuscule letters existed, but the difference between the two variants was initially stylistic rather than orthographic and the writing system was still basically unicameral: a given handwritten document could use either one style or the other but these were not mixed.". Is that enough to answer the question?
Answer: yes
