 For those using github's copilot (free for educators), it's very convenient to have the natural language statements
 right next to the Lean to be formalized. So we write the blueprint TeX right in the *.lean document, separated by
 delimiters `/-%% text here %%-/` for multi-line and `--%% text here` for single-line TeX. The code automatically
 scrapes these and populates the blueprint accordingly.
