nested_curly_braces

if there is a prose block containing curly braces, { such as this one } they should be treated as part of the prose.
Matching braces that end a line — including adjacent pairs like { { SITE_URL } } — stay in the body; they must not close the enclosing idea.
A lone `}` on its own line still closes the structural block so an unbalanced prose `{` cannot swallow the idea closer.
