You need a single HTML file for a landing page, pricing sheet, or marketing site, and you don't want to write CSS from scratch. This skill copies a pre-built template with typography and spacing already dialed in, then you paste section layouts from a reference library: hero, feature grid, stat blocks, comparison tables. The template enforces a single accent color budget and serif headings. It's explicitly not for writing new styles or building multi-page apps. The workflow is rigid by design: read the seed file first, pick your sections before writing copy, fill in the placeholders, ship the artifact. Good for when you want something clean in one pass without fighting a framework.
