html-artifact

Build one self-contained HTML file — no build step, no dependencies, no CDN — to explain, plan, report, review, diagram, compare, or prototype something a human should read, share, or poke at. Use when the deliverable has color, layout, diagrams, tables, or interaction, or when the user asks for an artifact, explainer, plan write-up, diagram, or design variants. Not for markdown-shaped notes, brand-matching a known site's look, or generative canvas art.
