@ctietze It’s the default of the Markdown.it plugin I’m using in Kitten (https://github.com/nagaozen/markdown-it-toc-done-right?tab=readme-ov-file#markdown-it-toc-done-right)
Also fits with some of the other additions I made (e.g,. [code] as alias for backticks when adding markdown directly to JS template strings) so it’s internally consistent :)
