+# To AI Agent: Complete Component Relocation - Move Navigation Tabs to Top Header and Fix Button Text Wrapping
+
+## 1. Context & Structural Defects Analysis
+We are fixing a persistent UI layout failure on the mobile view (`yotrip.labz.io.vn`) as highlighted in the annotated screenshot `image_c61225.png`:
+
+- **Component Misplacement (Lower Red Box):** The sub-navigation tabs (`Lộ trình`, `Chi phí`, `Ảnh`, `Trò chuyện`...) are currently detached and floating erratically in the middle of the chat history viewport, overlapping message bubbles.
+- **Empty Empty Top Gap (Upper Red Box):** There is an empty dark/blank bar container sitting directly below the Main Tour Title Header ("Hoa vàng cỏ xanh 20...").
+- **Text Wrapping Bug:** The labels on the floating navigation items are wrapping onto multiple lines (e.g., `Lộ\ntrình`, `Chi\nphí`), ruining the horizontal tab presentation.
+
+---
+
+## 2. Refactoring Objectives
+1. **DOM Relocation:** Completely extract the Sub-Navigation Tabs out of the chat message block. Relocate and mount it directly into the upper red box zone so it sits flush immediately underneath the Main Tour Header.
+2. **Text & Width Optimization:** Enforce strict styles on the tab container so that all navigation buttons adjust dynamically to fit within the viewport width. The button text names **MUST NOT** wrap down to a new line (`white-space: nowrap`).
+
+---
+
+## 3. Targeted Fix Instructions
+
+### Step 1: Correct the DOM / React Component Tree Hierarchy
+Ensure the navigation component sits inside the sticky top layout zone, completely separated from the scrollable chat list container:
+
+```html
+<div class="chat-viewport-wrapper">
+  
+  <div class="fixed-top-header-block">
+    <header class="main-tour-header">
+      </header>
+
+    <nav class="sub-navigation-tabs">
+      <button class="nav-tab-item">Lộ trình</button>
+      <button class="nav-tab-item">Chi phí</button>
+      <button class="nav-tab-item">Ảnh</button>
+      <button class="nav-tab-item active">Trò chuyện</button>
+      <button class="nav-tab-item">Thành viên</button>
+      <button class="nav-tab-item">Cài đặt</button>
+    </nav>
+  </div>
+
+  <main class="chat-messages-scroll-area">
+    </main>
+
+</div>
+
+### Step 2: Apply CSS/Tailwind Rules for Button Shrinkage & Single-Line Restraints
+Apply these structural adjustments to make sure the tabs fill the screen width evenly without line breaks:
+
+/* Container for header components stacked on top */
+.fixed-top-header-block {
+  display: flex !important;
+  flex-direction: column !important;
+  width: 100% !important;
+  position: sticky !important;
+  top: 0 !important;
+  z-index: 50 !important;
+  background-color: #ffffff;
+}
+
+/* FIX: Ensure tabs fit inside the viewport layout cleanly */
+.sub-navigation-tabs {
+  display: flex !important;
+  width: 100% !important;
+  margin: 0 !important;
+  padding: 4px 8px !important; /* Tight padding to utilize screen real estate */
+  border-radius: 0 !important;
+  box-shadow: none !important;
+  border-bottom: 1px solid #e5e7eb;
+  background-color: #ffffff;
+  
+  /* Distribute items evenly across the width */
+  justify-content: space-between !important; 
+  align-items: center !important;
+}
+
+/* FIX: Absolute enforcement of no word-wrapping on buttons */
+.nav-tab-item {
+  display: flex !important;
+  flex-direction: column !important; /* Stack icon and text if applicable */
+  align-items: center !important;
+  justify-content: center !important;
+  flex: 1 1 0% !important;         /* Allow dynamic even shrinkage */
+  min-width: 0 !important;          /* Overcomes default flex minimums */
+  
+  /* Text layout fixes */
+  white-space: nowrap !important;   /* PREVENT TEXT FROM WRAPPING TO NEW LINE */
+  font-size: 11px !important;       /* Scaled down to prevent out-of-bounds clipping */
+  padding: 4px 2px !important;
+  text-align: center !important;
+}
+
+/* Handle icon sizes inside tabs if applicable */
+.nav-tab-item svg, .nav-tab-item i {
+  font-size: 16px !important;
+  margin-bottom: 2px !important;
+}
+
+## 4. Verification Check for AI Agent
+[ ] Verify that the navigation row is no longer hovering over the chat text bubble flow.
+
+[ ] Confirm there is zero dead space or black margin layers between the tour header and the navigation buttons.
+
+[ ] Inspect text elements for words like "Lộ trình" and "Chi phí"—they must read completely on a single line horizontally.

+# To AI Agent: Refactor Itinerary Timeline into an Exclusive File Tree Directory System (Single Expansion Mode)
+
+## 1. Context & Architectural Analogy
+We are refactoring the `ItineraryTimeline` component on the mobile view (`yotrip.labz.io.vn`) using a **File Tree Directory System** analogy:
+- **Parent Folders ("Thư mục mẹ"):** Represented by the Stages ("Chặng 1", "Chặng 2"...).
+- **Child Nodes ("Thư mục con"):** Represented by the Locations/Destinations inside that stage (`Trần Cao Vân`, `Đồng Khởi`...).
+
+### CRITICAL LOGIC CONSTRAINT (Exclusive Accordion):
+- When a Parent Folder (Stage) is **collapsed**, all of its Child Nodes (Locations) must immediately hide cleanly inside it.
+- **Single Expansion Rule:** The system must enforce an **exclusive single-expansion mode**. On the entire timeline screen, **MAXIMUM ONE** Parent Folder can be expanded at any given time. 
+- Opening/Expanding a new Stage folder must **automatically collapse** whichever Stage folder was previously open.
+
+---
+
+## 2. State Management Specification (For Script/Logic Implementation)
+
+To enforce the "Maximum 1 Expanded Folder" rule, do NOT use isolated individual boolean flags for each stage. Instead, implement a centralized single-active-state variable:
+
+```javascript
+// Example React State Hook Blueprint:
+// Track the ID or index of the single active expanded stage folder. 
+// If null, all stages are collapsed.
+const [expandedStageId, setExpandedStageId] = useState(initialStageId);
+
+const handleStageToggle = (stageId) => {
+  // If clicking the already open folder, close it. Otherwise, open the new one and shut the rest.
+  setExpandedStageId(prevId => prevId === stageId ? null : stageId);
+};
+
+## 3. Component DOM Tree & CSS Blueprint
+### A. Component Layout Structure
+
+<div class="file-tree-itinerary-container">
+  
+  <div class="fixed-top-header-block">

+  width: 100vw !important;

+  padding: 12px 16px !important;
+  display: flex;
+  align-items: center;
+  background-color: #ffffff;
+  cursor: pointer;
+  /* Sticky behavior remains active when scrolling within an open directory */
+  position: sticky !important;
+  top: 0px; 
+  z-index: 30;
+}
+
+/* CSS Grid Transition Engine for smooth directory expansions */
+.folder-child-content-box {
+  display: grid !important;
+  grid-template-rows: 0fr;
+  transition: grid-template-rows 0.25s cubic-bezier(0.4, 0, 0.2, 1) !important;
+  width: 100%;
+}
+
+.child-nodes-list {
+  overflow: hidden;
+  min-height: 0px;
+  padding: 16px;
+  display: flex;
+  flex-direction: column;
+  gap: 12px;
+}
+
+/* --- MUTUALLY EXCLUSIVE STATE STYLES --- */
+
+/* Collapsed Folder: Sub-files shrink immediately to 0 height */
+.folder-node-wrapper.collapsed .folder-child-content-box {
+  grid-template-rows: 0fr !important;
+}
+
+/* Expanded Folder: Opens dynamically to accommodate dynamic content height */
+.folder-node-wrapper.expanded .folder-child-content-box {
+  grid-template-rows: 1fr !important;
+}
+
+## 4. Acceptance Criteria for AI Agent Verification
+[ ] Mutually Exclusive Test: Clicking an inactive Stage header while another stage is open must trigger a simultaneous transition: the old stage collapses back into a tight header row, and the clicked stage expands its location cards.
+
+[ ] Zero-Gap Validation: All collapsed folder components must sit completely flush against the top tab block and one another, eliminating all gray margin bleeding.
+
+[ ] Under-Clip Containment: When scrolling a long open folder, the list items must slide behind their sticky active parent folder row and disappear without visual overlapping artifacts.
