+## Mobile Material Design
+
+> **Full Documentation:** [docs/MOBILE_PATTERNS.md](./MOBILE_PATTERNS.md)
+
+ROA2WEB includes a complete mobile component library following Material Design 3 principles. All mobile components are designed for touch interactions and support both light and dark themes.
+
+### Available Components
+
+| Component | Location | Description |
+|-----------|----------|-------------|
+| `MobileTopBar` | `@shared/components/mobile/` | Fixed top bar with title, back/menu buttons, and actions |
+| `MobileBottomNav` | `@shared/components/mobile/` | Fixed bottom navigation with router integration |
+| `MobileSelectionFooter` | `@shared/components/mobile/` | Slide-up action bar for batch operations |
+| `BottomSheet` | `@shared/components/mobile/` | Modal sheet for filters and forms |
+| `SwipeableCards` | `@shared/components/mobile/` | Touch carousel for KPI cards |
+
+### Mobile Breakpoints
+
+```css
+/* Mobile-first breakpoints */
+@media (max-width: 768px) {
+  /* Mobile styles - this is where mobile components activate */
+}
+
+@media (min-width: 769px) {
+  /* Tablet and desktop styles */
+}
+
+@media (min-width: 1024px) {
+  /* Desktop-only styles */
+}
+```
+
+### Key Mobile Layout Tokens
+
+| Token | Value | Use |
+|-------|-------|-----|
+| `--header-height` | 56px | TopBar and BottomNav height |
+| Touch target | 48×48px | Minimum button/tap area |
+| `--z-fixed` | 1030 | Fixed navigation elements |
+| `--z-modal` | 1050 | BottomSheet and overlays |
+
+### Quick Example
+
+```vue
+<template>
+  <div class="mobile-view">
+    <MobileTopBar title="My View" :showMenu="true" />
+
+    <main class="mobile-content">
+      <!-- Content with padding for fixed bars -->
+    </main>
+
+    <MobileBottomNav />
+  </div>
+</template>
+
+<style scoped>
+.mobile-content {
+  padding-top: 56px;    /* MobileTopBar */
+  padding-bottom: 56px; /* MobileBottomNav */
+  min-height: 100vh;
+}
+</style>
+```
