 The objective is to build a multi-platform chat overlay SaaS (Software as a Service) for streamers. The service will aggregate chat from Twitch and YouTube into a single, customizable browser source for use in streaming software like OBS.

 ### Current Status
-The project is in **Phase 1: User Authentication & Database**. Most of this phase is complete.
-*   A solid FastAPI application skeleton is in place.
-*   The database schema (`User`, `Setting` models) is defined using SQLAlchemy and a SQLite database.
-*   A secure Twitch OAuth2 authentication flow is fully functional. It correctly:
-    1.  Redirects users to Twitch.
-    2.  Handles the callback.
-    3.  Exchanges the authorization code for tokens.
-    4.  Fetches user details from the Twitch API.
-    5.  Encrypts the tokens using the `cryptography` library.
-    6.  Saves or updates the user's record in the database.
+**Phases 1, 2, and 3 are complete.** The application is now a fully functional chat overlay service for Twitch.
+*   **Phase 1 (Authentication):** A secure Twitch OAuth2 flow is implemented, with user data and encrypted tokens stored in a SQLite database.
+*   **Phase 2 (Dashboard & Configuration):** A dynamic user dashboard is available after login. It includes a theme switcher (light/dark), a theme selector for the overlay, and a full CRUD system for users to create and manage their own private CSS themes.
+*   **Phase 3 (Real-time Chat):** A decoupled background listener manager successfully starts `twitchio` listeners for each user. A WebSocket manager broadcasts incoming chat messages to the correct user's overlay in real-time.
 *   A basic HTML login page is served at the root URL (`/`).
-*   Configuration and secrets are managed securely via a `config.py` file that reads from a `.env` file.

 ### Core Architecture
 The project is built on the "hybrid architecture" detailed in the `RESEARCH_REPORT.md`:
 *   **Authentication:** Always use the official, secure OAuth2 flows for each platform.

+# Analysis of Failed Approach #6: `twitchio` Initialization Conflict
+
+## 1. Executive Summary
+
+This document outlines the reasons for the persistent failure to initialize the `twitchio` chat listeners within our FastAPI application. Our attempts have been caught in a cyclical error pattern, switching between a `TypeError` for a missing argument and an `OSError` for a port conflict.
+
+The root cause is a fundamental design conflict: we are attempting to use a high-level abstraction (`twitchio.ext.commands.Bot`) in a way it is not designed for. This class is architected as a **standalone application** that includes its own web server for handling Twitch EventSub. Our project requires a simple, "headless" IRC client component to be embedded within our existing FastAPI web server. The `commands.Bot` class is not this component, and our attempts to force it into this role have failed.
+
+**Conclusion:** Continuing to patch this approach is inefficient and unreliable. A new strategy is required.
+
+## 2. The Cyclical Error Pattern
+
+Our efforts have resulted in a loop between three primary, contradictory errors, demonstrating the library's conflicting internal states.
+
+### Error A: `OSError: [Errno 98] address already in use`
+
+*   **Trigger:** Occurs with a default `twitchio.ext.commands.Bot` initialization.
+*   **Implication:** The library, by default, attempts to start its own `AiohttpAdapter` web server (e.g., on port 4343) for EventSub, which immediately conflicts with our main Uvicorn process or any other service.
+
+### Error B: `TypeError: Bot.__init__() missing 1 required keyword-only argument: 'bot_id'`
+
+*   **Trigger:** Occurs when we successfully disable the internal web server using a `NullAdapter`.
+*   **Implication:** By disabling the web server, we seem to place the `Bot` into a different initialization path that now strictly requires the `bot_id` argument, which it previously did not.
+
+### Error C: Back to `OSError: [Errno 98] address already in use`
+
+*   **Trigger:** Occurs when we satisfy Error B by providing the `bot_id` while the `NullAdapter` is active.
+*   **Implication:** This is the most critical failure. It demonstrates that providing the `bot_id` causes the library's constructor to **ignore our `NullAdapter`** and fall back to its default behavior of starting a web server, thus bringing us back to Error A.
+
+### Error D: `TypeError: Client.start() got an unexpected keyword argument 'web_server'`
+
+*   **Trigger:** Occurred when we attempted to bypass the adapter system entirely and use `bot.start(web_server=False)`.
+*   **Implication:** This proves the `start()` method's API does not support this parameter, closing another potential avenue for controlling the library's behavior.
+
+## 3. The Homelab & Nginx Proxy Manager Conflict
+
+This architectural mismatch is especially problematic in our homelab environment using Nginx Proxy Manager.
+
+1.  **Single Entry Point:** Our architecture is designed for a single entry point. Nginx Proxy Manager accepts all traffic on ports 80/443 and forwards it to a single backend service: our FastAPI application on port 8000.
+
+2.  **Unwanted Second Service:** `twitchio`'s attempt to start a second web server on a different port (e.g., 4343) is fundamentally incompatible with this model. It forces us to treat our single Python application as two distinct backend services.
+
+3.  **Unnecessary Complexity:** To make this work, we would have to configure Nginx Proxy Manager with complex location-based routing rules (e.g., route `/` to port 8000, but route `/eventsub` to port 4343). This is brittle, hard to maintain, and completely unnecessary for our goal, which is **IRC chat only**.
+
+4.  **Port Conflicts:** In a managed homelab environment (using Docker, etc.), ports are explicitly allocated resources. A library that randomly tries to bind to an arbitrary port is an unstable and unpredictable component that will inevitably conflict with other services.
+
+## 4. Root Cause: Architectural Mismatch
+
+The `twitchio.ext.commands.Bot` class is a powerful, feature-rich tool designed for building **standalone bots**. It is not designed to be a simple, embeddable component within a larger web application that has its own server.
+
+Our application architecture requires a "headless" IRC client—a component that does nothing but connect to Twitch's chat servers and listen for messages. The `commands.Bot` class is not that component. It brings along a suite of other features, including its own web server, which we cannot reliably disable.
+
+Our attempts to "trick" the library into behaving like a simple client have failed because we are fighting against its core design:
+
+## 5. Recommendation: Pivot to a Low-Level Client
+
+We must abandon the use of `twitchio.ext.commands.Bot`.
+
+The correct path forward is to use the lower-level `twitchio.Client` class instead. This class is designed to be a more fundamental IRC client without the high-level command handling and, crucially, without the tightly coupled web server components.
+
+By switching to `twitchio.Client`, we can build a `TwitchBot` class that is truly "headless" and will integrate cleanly into our existing FastAPI application and `ListenerManager` without causing port conflicts or argument mismatches. This aligns our implementation with our architectural needs.

+    <h2>Custom Overlay CSS Guide</h2>
+    <p>This guide will help you create your own custom CSS for the chat overlay. Your CSS is applied on top of a base stylesheet, so you only need to override the styles you want to change.</p>
+</div>
+
+<div class="card">
+    <h3>HTML Structure</h3>
+    <p>Your CSS will be applied to a simple HTML structure. Here are the key classes you can target:</p>
+    <ul>
+        <li><code>.chat-container</code>: The main container holding all messages.</li>
+        <li><code>.chat-message</code>: The container for a single message, including the username and text.</li>
+        <li><code>.username</code>: The part of the message that shows the chatter's name.</li>
+        <li><code>.message-text</code>: The actual content of the chat message.</li>
+    </ul>
+    <p>The <code>body</code> of the overlay is transparent by default, so you only need to style the message elements.</p>
+</div>
+
+<div class="card">
+    <h3>Example: "Bubbly" Theme</h3>
+    <p>Here is a simple example to get you started. This creates chat bubbles with a gradient background.</p>
+    <pre><code>body {
