**4. CORE FEATURES & USER FLOW:**

*   **Authentication:**
    *   **Flow:** User lands on the homepage. Clicks "Sign Up" or "Login". Redirected to the Auth page (`/auth`). User enters email/password. On successful login, redirect to the Dashboard (`/dashboard`). On sign up, create user in DB, log them in, redirect to Dashboard.
    *   **Edge Case:** Invalid credentials -> show error message. Already logged in -> redirect to Dashboard.

*   **Dashboard (`/dashboard`):**
    *   **Flow:** Authenticated users see a list of their created LED strip configurations and visualization presets. Options to create new ones or edit existing ones.
    *   **Components:** `DashboardLayout`, `StripList`, `VisualizationList`, `CreateNewButton`.
    *   **State:** Fetch user's strips and visualizations on mount. Manage loading and error states.

*   **LED Strip Configuration (`/dashboard/strips/new` or `/dashboard/strips/[id]/edit`):**
    *   **Flow:** User clicks "Create New Strip" or "Edit". Navigates to the configuration page. User selects strip type (WS2812B, APA102, etc.), enters LED count, name, and optionally other parameters like chipset. User saves the configuration. On edit, pre-fill form with existing data.
    *   **Components:** `StripForm` (using React Hook Form, Zod validation), `Input`, `Select`, `NumberInput`, `ColorPicker` (for potential defaults), `SaveButton`.
    *   **API:** POST `/api/strips` (create), PUT `/api/strips/[id]` (update), GET `/api/strips` (fetch list), GET `/api/strips/[id]` (fetch single).
    *   **Validation:** `ledCount` must be > 0. `name` is required.

*   **Visualization Editor (`/dashboard/visualizations/new` or `/dashboard/visualizations/[id]/edit`):**
    *   **Flow:** User clicks "Create New Visualization" or "Edit". Navigates to the editor. User selects a configured `ledStripId`. Chooses an `algorithm` (e.g., "Frequency Spectrum", "Amplitude Mapping"). Configures algorithm parameters via dynamic form elements. Selects/creates a `colorPalette`. Chooses an `effectType` (e.g., "Scroll", "Pulse"). Sets `animationSpeed`. Saves the preset.
    *   **Components:** `VisualizationForm`, `Select` (for strip, algorithm, effect), Dynamic Parameter Inputs based on selected algorithm, `ColorPaletteSelector` (can be a simple array of hex inputs for MVP or a more advanced gradient picker), `Slider` (for speed, sensitivity), `SaveButton`.
    *   **API:** POST `/api/visualizations` (create), PUT `/api/visualizations/[id]` (update), GET `/api/visualizations` (fetch list), GET `/api/visualizations/[id]` (fetch single).
    *   **Edge Cases:** Algorithm parameter forms must adapt to the selected algorithm.

*   **Real-time Preview & Control (`/visualize/[id]`):**
    *   **Flow:** User selects a saved visualization preset and clicks "Visualize" (or similar). Navigates to a dedicated visualization page. This page attempts to connect to the user's hardware (via WebSocket). It takes audio input (either uploaded track playback or live mic input) and processes it using the selected algorithm and parameters. The processed data is translated into LED commands and sent to the connected hardware.
    *   **Components:** `AudioPlayer` (if using uploaded track), `LiveAudioInput` (using Web Audio API `getUserMedia`), `VisualizationCanvas` (renders the effect in the browser as a preview and sends data via WebSocket), `ControlPanel` (play/pause, volume, select visualization).
    *   **API:** WebSocket endpoint (`/ws/sync`) to send commands to hardware.
    *   **Real-time:** Use Web Audio API for FFT analysis. Send small, frequent updates over WebSockets.

**5. API & DATA FETCHING:**

*   **Next.js API Routes (App Router):** All API routes will be under `src/app/api/`. Example: `src/app/api/strips/route.ts`.
*   **REST Endpoints:** Standard CRUD operations for `strips` and `visualizations` (GET, POST, PUT, DELETE).
*   **Data Fetching:** Use server components where possible for initial data loading. Use client components with `fetch` or a library like SWR/React Query for dynamic data and form submissions.
*   **WebSocket:** Establish a WebSocket connection from the client (visualization page) to the backend server for real-time command transmission to the hardware. The backend will need to manage these connections and relay data.
*   **Request/Response:** Use JSON for all API requests/responses. Implement clear error handling (e.g., HTTP status codes, JSON error messages).
