I want to vertically center the content of all pages. I followed the approach in https://tex.stackexchange.com/a/155734/91605, but alignment becomes increasingly skewed from actual center when as the body font size grows. This happens no matter whether there is a single line of text or many. How can I fix this?
\setuppagenumbering[location=] \setupbodyfont[100pt] \showframe \starttext \dontleavehmode\vfill text \vfill \stoptext
