-### Clickable Cards & Accessibility
-
-**Date:** 2026-01-01
-**Context:** Making `motion.div` or non-button elements accessible
-
-When making a div clickable (like a card), you must ensure it's accessible:
-1.  **Role**: Add `role="button"`.
-2.  **TabIndex**: Add `tabIndex={0}` so it's focusable.
-3.  **Keyboard Handler**: Add `onKeyDown` to handle 'Enter' and 'Space'.
-4.  **Label**: Add `aria-label` to describe the action.
-5.  **Focus Styles**: Add visible focus styles (e.g., `focus:ring`).
-
-```tsx
-<motion.div
-  onClick={handleClick}
-  role="button"
-  tabIndex={0}
-  aria-label="View Details"
-  onKeyDown={(e) => {
-    if (e.key === 'Enter' || e.key === ' ') {
-      e.preventDefault();
-      handleClick();
-    }
-  }}

-### Form Validation Pattern
-
-**Date:** 2026-01-01
-**Context:** Implemented in Auth.tsx
-
-```tsx
-type FormErrors = { [key: string]: string };
-const [fieldErrors, setFieldErrors] = useState<FormErrors>({});
-
-// 1. Validation Logic
-const validate = () => {
-  const newErrors: FormErrors = {};
-  if (!email) newErrors.email = 'Required';
-  setFieldErrors(newErrors);
-  return Object.keys(newErrors).length === 0;
-};
-
-// 2. Clear on type
-const clearFieldError = (field: string) => {
-  if (fieldErrors[field]) {
-    setFieldErrors(prev => ({ ...prev, [field]: undefined }));
-  }
-};
-
-// 3. Render with accessibility
-<form onSubmit={handleSubmit} noValidate>
-  <Input
-    error={fieldErrors.email}
-    onChange={(e) => {
-      setEmail(e.target.value);
-      clearFieldError('email');
-    }}
-    // Input component handles:
-    // aria-invalid={!!error}
-    // aria-describedby={`${id}-error`}
-    // Error message has id={`${id}-error`} and role="alert"
-  />

+### List Loading vs. Refreshing
+
+**Date:** 2026-01-01
+**Context:** Implementing pull-to-refresh on mobile lists
+
+Always separate `isLoading` (initial blocking load) from `isRefreshing` (pull-to-refresh).
+
+**Bad Pattern:**
+
+```javascript
+<FlatList
+  refreshing={isLoading}
+  onRefresh={fetchData}
+/>
+{isLoading ? <Spinner /> : <List />} // List disappears on refresh!
+```
+
+**Good Pattern:**
+
+```javascript
+const [isLoading, setIsLoading] = useState(true); // Initial load
+const [isRefreshing, setIsRefreshing] = useState(false); // Pull-to-refresh
+
+const fetchData = async (refresh = false) => {
+  if (refresh) setIsRefreshing(true); else setIsLoading(true);
+  // ... fetch data
+  setIsLoading(false);
+  setIsRefreshing(false);
+}
+
+// ...
+
+{isLoading ? <Spinner /> : (
+  <FlatList
+    refreshing={isRefreshing}
+    onRefresh={() => fetchData(true)}
+  />
+)}
+```
+
+**Also:** Use `expo-haptics` for tactile feedback on refresh triggers.

-### Playwright Verification Patterns
-**Date:** 2026-01-01
-**Context:** Verifying accessibility changes with Playwright scripts
-
-When writing Playwright scripts to verify frontend changes without backend:
-
-1. **Auth Mocking:** You must mock `/users/me` persistently. If this call fails or returns 401, `AuthContext` will force a redirect to login, breaking navigation tests.
-2. **Route Matching:** Use specific route patterns (e.g., `**/users/me`) and ensure they don't accidentally swallow longer paths (like `**/users/me/balance-summary`) if using wildcards carelessly. Register specific paths before general ones if using `page.route` order dependence, or use specific globs.
-3. **Response Structure:** Mocks must match the structure expected by `axios` interceptors and components. If `axios` returns `res.data` as the body, and the component expects `res.data.groups`, the mock body should be `{"groups": [...]}` (not `{"data": {"groups": ...}}`).
