 Nostr_Login_Lite
 ===========
+
+## Floating Tab API
+
+Configure persistent floating tab for login/logout:
+
+```javascript
+await NOSTR_LOGIN_LITE.init({
+  floatingTab: {
+    enabled: true,
+    hPosition: 0.95,        // 0.0-1.0 or '95%' from left
+    vPosition: 0.5,         // 0.0-1.0 or '50%' from top
+    appearance: {
+      style: 'pill',        // 'pill', 'square', 'circle', 'minimal'
+      theme: 'auto',        // 'auto', 'light', 'dark'
+      icon: '🔐',
+      text: 'Login'
+    },
+    behavior: {
+      hideWhenAuthenticated: false,
+      showUserInfo: true,
+      autoSlide: true
+    },
+    animation: {
+      slideDirection: 'auto' // 'auto', 'left', 'right', 'up', 'down'
+    }
+  }
+});
+```
+
+Control methods:
+```javascript
+NOSTR_LOGIN_LITE.showFloatingTab();
+NOSTR_LOGIN_LITE.hideFloatingTab();
+NOSTR_LOGIN_LITE.updateFloatingTab(options);
+NOSTR_LOGIN_LITE.destroyFloatingTab();
+```
+
+## Embedded Modal API
+
+Embed login interface directly into page element:
+
+```javascript
+// Initialize library first
+await NOSTR_LOGIN_LITE.init({
+  methods: {
+    extension: true,
+    local: true,
+    readonly: true
+  }
+});
+
+// Embed into container
+const modal = NOSTR_LOGIN_LITE.embed('#login-container', {
+  title: 'Login',
+  showHeader: true,
+  seamless: false  // true = no borders/shadows, blends into page
+});
+```
+
+Container can be CSS selector or DOM element. Modal renders inline without backdrop overlay.
