What problem does it solve? Producing polished, self-contained HTML artifacts (documents, dashboards, status boards, comparisons, system explainers) usually requires ad-hoc styling decisions and manual bundling of CSS and JavaScript. This Skill supplies an approved visual language, reusable page shapes, and a renderer so every artifact ships as one readable, light-and-dark HTML file. ## Core Features & Use Cases - Five approved page shapes: document, dashboard, status board, comparison, and system explainer templates with shared Plain CSS tokens for light and dark appearances. - Self-contained renderer: scripts/render.py embeds CSS, JavaScript, and content into a single portable HTML file, with a gallery mode for comparing examples. - Interactive diagram and dashboard assets: a pan/zoom architecture graph component and a shadcn/ui React log explorer with an offline build for dense data exploration. - Use Case: Turn a design proposal into a standalone HTML document with footnotes and an embedded diagram, then verify it at desktop and 390 px widths in both appearances before sharing it as a single file. ## Quick Start Use the html-artifact-style skill to turn my design proposal into a standalone Plain-style HTML document with a system diagram.
