+# Responsive layout vs data fetching
+
+When adding or changing pages with mobile/desktop views:
+
+## UI layer (responsive)
+
+- Switch layouts with **`v-show`**, not **`v-if`**, so resize does not destroy child components.
+- Prefer `ResponsiveViewPair` (`src/layouts/components/ResponsiveViewPair.vue`) or the home shell pattern.
+- Keep **`<router-view>`** outside responsive chrome wrappers (header/topbar only in chrome components).
+- Modal vs ActionSheet may use `v-if` by breakpoint; they must not own initial page data fetching.
+
+## Data layer (fetch once)
+
+- Call the page composable **once** in the route `index.vue` shell (e.g. `useXPage()` / `useXPageProvider()`).
+- Put `onMounted` API calls only in that shell composable, never in `mobile/*` or `desktop/*` views.
+- Mobile/Desktop views use **`useXPageContext()`** (provide/inject) — read-only UI.
+- Do not call APIs inside `useDesktopBreakpoint()` watchers.
+
+## Shared caches
+
+- Use `runOnceAsync` (`src/composables/useOnceAsync.ts`) for store-level dedup when the same endpoint may be hit from multiple mounts.
+- Reuse existing module caches (`useWalletAssets`, Pinia stores) before adding new fetch logic.
+
+## Verify
+
+- Open Network tab, load a page, resize across 768px — **no duplicate requests** for the same endpoint.
