Generate a complete HTML-slide Design System markdown file from a reference URL. Studies the page's color palette, typography, logo, and aesthetic mood, then writes a Design System that bakes in proven engineering rules (1280×720 fit contract, three-layer overflow safety net, single-absorber rule, mobile inline-flex trap catch-all, flip-card mobile fix, logo-as-SVG-symbol-with-currentColor pattern, 12px readability floor) while letting the brand identity drive the visuals. Use this whenever the user gives you a URL and asks to "build a design system from this site," "extract a design system from", "make slides like this brand," "skin slides to match this site's visual language," or wants to author HTML slides in the visual language of any specific website. Also use when the user names a brand site as a slide-deck reference, even if they don't say "design system" explicitly.
