## 1. Objective
*   Solve the "awkward UX" on mobile devices where the full-screen AI Sidepanel blocks context.
*   Implement a "Floating Bottom Bar" (Bottom Sheet) style UI for mobile (`md:hidden`).
*   Ensure strict separation from the PC version (`md:block`) to prevent side effects.

## 2. Changes
### 2.1. New Component: `MobileAIBar.tsx`
*   **UI**: Floating FAB (Mini mode) + Bottom Sheet (Expanded mode).
*   **Features**:
    -   Integrated `AIWhispers` for voice feedback.
    -   Action buttons (Summarize, Structure, etc.).
    -   Streaming-like text result display.
    -   Clipboard/Apply actions.
*   **Path**: `nextapp/src/components/MobileAIBar.tsx`

### 2.2. Integration: `DocumentClient.tsx`
*   Imported `MobileAIBar`.
*   Wrapped `AISidepanel` in `<div className="hidden md:block">`.
*   Added `MobileAIBar` with `className` implicit in its design (renders only on mobile breakpoints).
*   **State Sharing**: reused `isAISidepanelOpen` state effectively to toggle visibility for both, controlled by CSS.

## 3. Verification Steps
1.  **PC View**:
    -   Resize window to > 768px.
    -   Click "AI Assistant" button.
    -   Confirm Sidepanel slides in from right.
    -   Confirm Mobile Bar is invisible.
2.  **Mobile View**:
    -   Resize window to < 768px.
    -   Confirm "AI 비서" floating button appears at bottom right.
    -   Click button OR use voice command "요약해줘".
    -   Confirm Bottom Sheet slides up.
    -   Confirm Sidepanel is invisible.
3.  **Functionality**:
    -   Test AI Summary on both views.
    -   Test "Apply to Document" on both views.

## 4. Final Polish (Phase 6) - 2026-02-18
*   **Auto-close**: Mobile AI Bar now closes automatically after text insertion for better visibility.
*   **Smart Numbering**: Implemented `detectNextNumbering` to automatically continue numbered lists (e.g., `1.` -> `2.`, `1.1.` -> `1.2.`) when inserting text.
