Start every sentence on a new line. Break any sentence over 80 characters across lines. Split at commas, conjunctions, or clause boundaries. Use 100 characters as the margin for `.tex` files. Indent every continuation line by two spaces. Apply to Markdown body, TeX paragraphs, and `.txt` prose. Apply to blockquotes and full-sentence list items too. Skip fenced code and inline code. Skip YAML or TOML frontmatter, tables, headings, and link references. Skip any line where a hard break changes rendered output. Preserve layout when a document already follows these rules. Reformat only the sentences you touch when a document does not follow them. Reflow the whole document only when asked.
