+## Brand Assets
+
+The design system ships logo assets as static files via package exports. These are not React components — they resolve to file URLs when imported via a bundler.
+
+| Export | Size | Use case |
+|--------|------|----------|
+| `@cameleer/design-system/logo` | Original | Full resolution for print/marketing |
+| `@cameleer/design-system/logo-16` | 16×16 | Browser tab favicon |
+| `@cameleer/design-system/logo-32` | 32×32 | Standard favicon, bookmarks |
+| `@cameleer/design-system/logo-48` | 48×48 | Windows taskbar |
+| `@cameleer/design-system/logo-180` | 180×180 | Apple touch icon |
+| `@cameleer/design-system/logo-192` | 192×192 | Android/PWA icon |
+| `@cameleer/design-system/logo-512` | 512×512 | PWA splash, og:image |
+| `@cameleer/design-system/logo-svg` | Vector | SVG logo for scalable usage |
+
+### Usage
+
+```tsx
+import logo from '@cameleer/design-system/logo-512'
+<img src={logo} alt="Cameleer3" />
+```
+
+```html
+<!-- Favicons in index.html -->
+<link rel="icon" type="image/png" sizes="32x32" href="/cameleer3-32.png">

+```
+
 ## Styling Rules
 
 - **CSS Modules only** — no inline styles except dynamic values (width, color from props)
