+// Control Methods
+NOSTR_LOGIN_LITE.launch();                    // Open login modal
+NOSTR_LOGIN_LITE.logout();                   // Clear authentication state
+NOSTR_LOGIN_LITE.switchTheme('dark');        // Change theme
+NOSTR_LOGIN_LITE.showFloatingTab();          // Show floating tab
+NOSTR_LOGIN_LITE.hideFloatingTab();          // Hide floating tab
+NOSTR_LOGIN_LITE.updateFloatingTab(options); // Update floating tab options
+NOSTR_LOGIN_LITE.toggleFloatingTab();        // Toggle floating tab visibility
 
-// After initialization, you can switch themes dynamically:
-NOSTR_LOGIN_LITE.switchTheme('dark');
-NOSTR_LOGIN_LITE.switchTheme('default');
-
-// Or customize individual theme variables:
-NOSTR_LOGIN_LITE.setThemeVariable('--nl-accent-color', '#00ff00');
-
+// Get Authentication State (Single Source of Truth)
+const authState = NOSTR_LOGIN_LITE.getAuthState();
+const isAuthenticated = !!authState;
+const userInfo = authState; // Contains { method, pubkey, etc. }
 ```
 
-Control methods:
-```javascript
-NOSTR_LOGIN_LITE.showFloatingTab();
-NOSTR_LOGIN_LITE.hideFloatingTab();
-NOSTR_LOGIN_LITE.updateFloatingTab(options);
-NOSTR_LOGIN_LITE.destroyFloatingTab();
-```
+**Authentication Persistence:**
+
+Two-tier configuration system:
+
+1. **`persistence: boolean`** - Master switch for authentication persistence
+   - `true` (default): Save authentication state for automatic restore
+   - `false`: No persistence - user must login fresh every time
+
+2. **`isolateSession: boolean`** - Storage location when persistence is enabled
+   - `false` (default): Use localStorage - shared across tabs/windows
+   - `true`: Use sessionStorage - isolated per tab/window
+
+**Use Cases for Session Isolation (`isolateSession: true`):**
+- Multi-tenant applications where different tabs need different users
+- Testing environments requiring separate authentication per tab
+- Privacy-focused applications that shouldn't share login state across tabs
