Use when someone hands you a finished long-form markdown document (a report, an essay, an archived article, a research write-up) and wants it turned into a single self-contained HTML file meant to be read or kept — not a slide deck, not a marketing page, not a redesign. Trigger on requests like "typeset this report as HTML", "make a clean reading page from this markdown", "archive this article as a standalone HTML I can keep", or "turn this write-up into a page I can send to a client". The skill assembles; it does not rewrite the author's words, add arguments, or add decoration.
