Wire up @codemirror/lang-markdown with a custom HighlightStyle to highlight headings, bold, italic, strikethrough, links, lists, blockquotes, and inline code in the raw CodeMirror editor. The custom frontmatter plugin is kept for YAML highlighting; its heading decoration is removed in favour of the language-based parser.
