structured-html-to-pptx

Convert structured HTML presentation documents (HTML decks where each slide is a div with class "slide" containing semantic CSS classes like .page-header, .action-title, .lead-in, .two-col, .info-table, .takeaway, .diagram) into fully editable PowerPoint .pptx files. Use this skill whenever a user wants to turn an HTML slide deck into PPTX — especially when they mention "HTML to PPTX", "資料をパワポにして", "ホームページの形式の資料をPowerPointに", "slide HTML to PPTX", "convert HTML deck", "編集可能なPPTX", or reference an HTML file that contains slide-shaped DOM with these class names. The output PPTX has native editable textboxes, native tables with proper borders, embedded SVG diagrams as PNG, and inline date-tag pills with red highlight backgrounds.
