Implement Phase 2 Frontend with Ant Design and verify Data Ingestion

- Created `frontend/` React+Vite app using Ant Design (Dark Theme).
- Implemented `App.jsx` to display listening history and calculated "Vibes".
- Updated `backend/app/ingest.py` to fix ReccoBeats ID parsing.
- Updated `backend/app/schemas.py` to expose audio features to the API.
- Updated `README.md` with detailed Docker hosting instructions.
- Added `TODO.md` for Phase 3 roadmap.
- Cleaned up test scripts.

 A personal analytics dashboard for your music listening habits, powered by Python, FastAPI, React, and Google Gemini AI.
 
-## Project Structure
-
-- `backend/`: FastAPI backend for data ingestion and API.
-  - `app/ingest.py`: Background worker that polls Spotify and enriches data via ReccoBeats.
-  - `app/services/`: Logic for Spotify, ReccoBeats, and Gemini APIs.
-  - `app/models.py`: Database schema (Tracks, PlayHistory).
-- `frontend/`: React + Vite frontend for visualizing the dashboard.
-- `docker-compose.yml`: For easy deployment.
-
 ## Features
 
 - **Continuous Ingestion**: Polls Spotify every 60 seconds to record your listening history.
 - **Data Enrichment**: Automatically fetches **Genres** (via Spotify) and **Audio Features** (Energy, BPM, Mood via ReccoBeats).
-- **Dashboard**: A responsive UI to view your history and stats.
+- **Dashboard**: A responsive UI (Ant Design) to view your history, stats, and "Vibes".
 - **AI Ready**: Database schema and environment prepared for Gemini AI integration.

+### 3. Run with Docker Compose
 
+#### Option A: Build from Source (Recommended for Dev/Modifications)
+
+Use this if you want to modify the code or ensure you are running the exact local version.
+
+1.  Clone the repository.
+2.  Ensure your `.env` file is set up.
+3.  Run:
     ```bash
     docker-compose up -d --build
     ```
 
-    This will:
-    - Build and start the **Backend** (port 8000).
-    - Build and start the **Frontend** (port 8991).
-    - Create a **Persistent Volume** at `/opt/mySpotify` (mapped to the container's database) to ensure **no data loss** during updates.
+#### Option B: Use Pre-built Image
 
-4.  **Access the Dashboard**:
-    Open your browser to `http://localhost:8991` (or your server IP).
+Use this if you just want to run the app without building locally.
 
-### 3. Data Persistence & Updates
+1.  Open `docker-compose.yml`.
+2.  Ensure the `backend` service uses the image: `ghcr.io/bnair123/musicanalyser:latest`.
+    *   *Note: If you want to force usage of the image and ignore local build context, you can comment out `build: context: ./backend` in the yaml, though Compose usually prefers build context if present.*
+3.  Ensure your `.env` file is set up.
+4.  Run:
+    ```bash
+    docker pull ghcr.io/bnair123/musicanalyser:latest
+    docker-compose up -d
+    ```
 
-- **Data**: All data is stored in `music.db` inside the container, which is mounted to `/opt/mySpotify/music.db` on your host machine.
-- **Migrations**: The project uses **Alembic** for database migrations. When you update the container image in the future, the backend will automatically apply any schema changes without deleting your data.

+# Future Roadmap & TODOs
+
+## Phase 3: AI Analysis & Insights
+
+### 1. Data Analysis Enhancements
+- [ ] **Timeframe Selection**:
+    - [ ] Update Backend API to accept timeframe parameters (e.g., `?range=30d`, `?range=year`, `?range=all`).
+    - [ ] Update Frontend to include a dropdown/toggle for these timeframes.
+- [ ] **Advanced Stats**:
+    - [ ] Top Artists / Tracks calculation for the selected period.
+    - [ ] Genre distribution charts (Pie/Bar chart).
+
+### 2. AI Integration (Gemini)
+- [ ] **Trigger Mechanism**:
+    - [ ] Add "Generate AI Report" button on the UI.
+    - [ ] (Optional) Schedule daily auto-generation.
+- [ ] **Prompt Engineering**:
+    - [ ] Design prompts to analyze:
+        - "Past 30 Days" (Monthly Vibe Check).
+        - "Overall" (Yearly/All-time evolution).
+    - [ ] Provide raw data (list of tracks + audio features) to Gemini.
+- [ ] **Storage**:
+    - [ ] Create `AnalysisReport` table to store generated HTML/Markdown reports.
+    - [ ] View past reports in a new "Insights" tab.
+
+### 3. Playlist Generation
+- [ ] **Concept**: "Daily Vibe Playlist" or "AI Recommended".
+- [ ] **Implementation**:
+    - [ ] Use ReccoBeats or Spotify Recommendations API.
+    - [ ] Seed with top 5 recent tracks.
+    - [ ] Filter by audio features (e.g., "High Energy" playlist).
+- [ ] **Action**:
+    - [ ] Add "Save to Spotify" button in the UI (Requires `playlist-modify-public` scope).
+
+### 4. Polish
+- [ ] **Mobile Responsiveness**: Ensure Ant Design tables and charts stack correctly on mobile.
+- [ ] **Error Handling**: Better UI feedback for API failures (e.g., expired tokens).

+# React + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the [TS template](https://github.com/vitejs/vite/tree/main/packages/create-vite/template-react-ts) for information on how to integrate TypeScript and [`typescript-eslint`](https://typescript-eslint.io) in your project.
