[studokim]

Changes

• embedded linter no longer complains on Bash- and Python-style comments in code blocks (previously it triggered the MD023 rule)

Before

After

MarkdownLint: no errors found

I've done this at 2025-05-14 locally on my computer, and the solution works for almost a year with files up to (at least) 7000 lines. The comment is preserved in code, it's fine to remove it before merging.
