WHAT IT CAPTURES
• Tech stack — frameworks (React, Vue, Angular, Svelte…), meta-frameworks (Next.js, Nuxt, Astro…), libraries, UI/CSS frameworks, analytics & bundler hints
• Design tokens — color palette (dominant / secondary / accent + real area share), typography (families, size scale, weights), spacing, radius and shadow scales, plus CSS custom properties
• Components — buttons, cards, header/nav/footer and more, re-rendered from their captured styles with type labels (filled / outline / text / nav / icon…)
• Images — every asset's natural & displayed size, ratio, format and role
