# Implement dnd-kit for Game View

**Status:** Planned
**Date:** 2025-12-18
**Description:**
Replace the standard HTML5 Drag and Drop API in `GameView.tsx` with `@dnd-kit/core` to ensure a consistent, high-performance, and touch-friendly user experience similar to the Deck Builder.

**Technical Reference:**
- **DeckBuilderView.tsx:** Uses `DndContext`, `useDraggable`, and `useDroppable` for managing card movements.
- **GameView.tsx:** Currently uses `onDragStart`, `onDrop`, etc.

**Plan:**
1.  **Install/Verify Dependencies:** `@dnd-kit/core` and `@dnd-kit/utilities` are already installed.
2.  **Create Draggable Wrapper:** Create a `DraggableCard` component that uses `useDraggable` to wrap `CardComponent`.
3.  **Create Droppable Zones:** Define `DroppableZone` components for Battlefield, Hand, Graveyard, Exile, etc.
4.  **Implement Context:** Wrap the main game area in `DndContext`.
5.  **Handle Drag Events:** Implement `onDragEnd` in `GameView` to handle logic previously in `handleZoneDrop` and `handleCardDrop`.
    -   Battlefield Drop -> `PLAY_LAND` / `CAST_SPELL` (positionless).
    -   Card on Card Drop -> `DECLARE_BLOCKERS` / `CAST_SPELL` (Targeting).
6.  **Refactor Rendering:** Update the rendering of cards in `GameView` to use the new `DraggableCard` wrapper.
