Single HTML Forge

One HTML file. No CDN, no build step, no external fetch at runtime. Opens the same on any machine and survives being emailed.

When to Use

• "HTMLスライドを作って" / "単一HTMLで資料にして" / "ブラウザーで開ける説明資料にして" / "サマリ画像を1枚"
• Handing a deck or explainer to someone who should not need PowerPoint
• Embedding images into a self-contained HTML artifact
• Re-verifying or editing an artifact this skill produced

Not for: PPTX output (this skill does not produce it), editable diagram source files, or anything needing a live server.
