# TV Dashboard Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** Build a full-screen rotating TV dashboard (4K, 3840x2160) that displays network topology with credentials, Odoo 19 project tasks (Kanban), and Odoo Calendar events.

**Architecture:** Python FastAPI backend with three modules (Odoo JSON-RPC client, nmap network scanner, YAML config manager) serving a React/Vite/Tailwind frontend. WebSocket for real-time updates. Three full-screen views rotate every 30 seconds with fade transitions.

**Tech Stack:** Python 3.11+, FastAPI, python-nmap, React 18, TypeScript, Vite, Tailwind CSS, D3.js, Framer Motion, Docker Compose

**Design doc:** `docs/plans/2026-02-15-tv-dashboard-design.md`

## Task 1: Backend Project Scaffolding

**Files:**
- Create: `backend/main.py`
- Create: `backend/requirements.txt`
- Create: `backend/config/settings.yaml`
- Create: `backend/config/services.yaml`
- Create: `backend/modules/__init__.py`
- Create: `backend/routers/__init__.py`
- Create: `backend/config/__init__.py`

**Step 1: Create requirements.txt**

```
fastapi==0.115.6
uvicorn[standard]==0.34.0
python-nmap==0.7.1
PyYAML==6.0.2
websockets==14.1
httpx==0.28.1
pydantic==2.10.4
pydantic-settings==2.7.1
```

**Step 2: Create settings.yaml with defaults**

```yaml
display:
  resolution: "3840x2160"
  rotation_interval_seconds: 30
  transition: "fade"
  theme: "dark"

odoo:
  url: "http://localhost:8069"
  database: "odoo"
  username: "admin"
  password: "admin"

refresh:
  odoo_minutes: 5
  network_minutes: 10
  ping_seconds: 60
```

**Step 3: Create services.yaml with example data**

```yaml
nodes:
  - name: "Router Principal"
    ip: "192.168.1.1"
    username: "admin"
    password: "admin"
    icon: "router"
    connections: []

  - name: "Servidor Ejemplo"
    ip: "192.168.1.10"
    username: "root"
    password: "password"
    public_url: "https://ejemplo.com"
    icon: "server"
    connections: ["Router Principal"]

network_scan:
  enabled: true
  subnet: "192.168.1.0/24"
  interval_minutes: 10
```

**Step 4: Create main.py with FastAPI app**

```python
from contextlib import asynccontextmanager
from fastapi import FastAPI
from fastapi.middleware.cors import CORSMiddleware


@asynccontextmanager
async def lifespan(app: FastAPI):
    # Startup
    yield
    # Shutdown


app = FastAPI(title="TV Dashboard API", lifespan=lifespan)

app.add_middleware(
    CORSMiddleware,
    allow_origins=["*"],
    allow_methods=["*"],
    allow_headers=["*"],
)


@app.get("/api/health")
async def health():
    return {"status": "ok"}
```

**Step 5: Create __init__.py files for packages**

Empty files for `backend/modules/__init__.py`, `backend/routers/__init__.py`, `backend/config/__init__.py`.

**Step 6: Verify the backend starts**

Run: `cd /root/Dashboard/backend && pip install -r requirements.txt && python -m uvicorn main:app --host 0.0.0.0 --port 8000 &`
Then: `curl http://localhost:8000/api/health`
Expected: `{"status":"ok"}`
Kill: `kill %1`

**Step 7: Commit**

```bash
git add backend/
git commit -m "feat: scaffold backend with FastAPI, config files, and health endpoint"
```

## Task 5: Backend API Routers

**Files:**
- Create: `backend/routers/network.py`
- Create: `backend/routers/tasks.py`
- Create: `backend/routers/calendar.py`
- Create: `backend/routers/services.py`
- Modify: `backend/main.py`

**Step 1: Create network router**

```python
from fastapi import APIRouter, Depends
from modules.config_manager import ConfigManager
from modules.network_scanner import NetworkScanner

router = APIRouter(prefix="/api/network", tags=["network"])


def get_config() -> ConfigManager:
    from main import app_config
    return app_config


@router.get("/topology")
async def get_topology(config: ConfigManager = Depends(get_config)):
    scan_config = config.get_network_scan_config()
    configured_nodes = config.get_nodes()

    scanner = NetworkScanner(subnet=scan_config.get("subnet", "192.168.1.0/24"))

    if scan_config.get("enabled", False):
        try:
            scan_data = scanner.scan()
            discovered = scanner.parse_scan_results(scan_data)
            nodes = scanner.merge_with_config(discovered, configured_nodes)
        except Exception:
            nodes = [{**n, "status": "unknown"} for n in configured_nodes]
    else:
        nodes = [{**n, "status": "unknown"} for n in configured_nodes]

    # Ping all nodes for current status
    ips = [n["ip"] for n in nodes]
    statuses = await scanner.ping_all(ips)
    for node in nodes:
        node["status"] = "up" if statuses.get(node["ip"], False) else "down"

    return {"nodes": nodes, "scan_enabled": scan_config.get("enabled", False)}
```

**Step 2: Create tasks router**

```python
from fastapi import APIRouter

router = APIRouter(prefix="/api/tasks", tags=["tasks"])


@router.get("/by-project")
async def get_tasks_by_project():
    from main import odoo_client
    projects = await odoo_client.get_projects()
    tasks = await odoo_client.get_tasks()

    # Group tasks by project
    result = []
    for project in projects:
        project_tasks = [t for t in tasks if t.get("project_id") and t["project_id"][0] == project["id"]]
        # Group by stage
        stages: dict[str, list] = {}
        for task in project_tasks:
            stage_name = task["stage_id"][1] if task.get("stage_id") else "Sin etapa"
            stages.setdefault(stage_name, []).append({
                "id": task["id"],
                "name": task["name"],
                "assigned": task.get("user_ids", []),
                "priority": task.get("priority", "0"),
                "deadline": task.get("date_deadline"),
                "kanban_state": task.get("kanban_state", "normal"),
            })
        result.append({
            "id": project["id"],
            "name": project["name"],
            "color": project.get("color", 0),
            "stages": stages,
        })

    return {"projects": result}
```

**Step 3: Create calendar router**

```python
from datetime import datetime, timedelta
from fastapi import APIRouter, Query

router = APIRouter(prefix="/api/calendar", tags=["calendar"])


@router.get("/events")
async def get_events(
    days: int = Query(default=7, ge=1, le=30),
):
    from main import odoo_client
    today = datetime.now().strftime("%Y-%m-%d")
    end = (datetime.now() + timedelta(days=days)).strftime("%Y-%m-%d")
    events = await odoo_client.get_calendar_events(date_from=today, date_to=end)
    return {"events": events, "date_from": today, "date_to": end}
```

**Step 4: Create services router (config/settings endpoint)**

```python
from fastapi import APIRouter

router = APIRouter(prefix="/api/services", tags=["services"])


@router.get("/config")
async def get_config():
    from main import app_config
    settings = app_config.get_settings()
    return {
        "display": settings.get("display", {}),
        "refresh": settings.get("refresh", {}),
    }
```

**Step 5: Update main.py to wire everything together**

```python
from contextlib import asynccontextmanager
from pathlib import Path

from fastapi import FastAPI
from fastapi.middleware.cors import CORSMiddleware

from modules.config_manager import ConfigManager
from modules.odoo_client import OdooClient

CONFIG_DIR = Path(__file__).parent / "config"

app_config = ConfigManager(
    settings_path=str(CONFIG_DIR / "settings.yaml"),
    services_path=str(CONFIG_DIR / "services.yaml"),
)

settings = app_config.get_settings()
odoo_settings = settings.get("odoo", {})

odoo_client = OdooClient(
    url=odoo_settings.get("url", "http://localhost:8069"),
    database=odoo_settings.get("database", "odoo"),
    username=odoo_settings.get("username", "admin"),
    password=odoo_settings.get("password", "admin"),
)


@asynccontextmanager
async def lifespan(app: FastAPI):
    # Authenticate with Odoo on startup
    try:
        await odoo_client.authenticate()
    except Exception as e:
        print(f"Warning: Could not connect to Odoo: {e}")
    yield


app = FastAPI(title="TV Dashboard API", lifespan=lifespan)

app.add_middleware(
    CORSMiddleware,
    allow_origins=["*"],
    allow_methods=["*"],
    allow_headers=["*"],
)

from routers import network, tasks, calendar, services

app.include_router(network.router)
app.include_router(tasks.router)
app.include_router(calendar.router)
app.include_router(services.router)


@app.get("/api/health")
async def health():
    return {"status": "ok", "odoo_connected": odoo_client.uid is not None}
```

**Step 6: Commit**

```bash
git add backend/routers/ backend/main.py
git commit -m "feat: add API routers for network, tasks, calendar, and services"
```

## Task 6: WebSocket for Real-Time Updates

**Files:**
- Create: `backend/routers/ws.py`
- Modify: `backend/main.py` (add ws router + background tasks)

**Step 1: Create WebSocket router**

```python
import asyncio
import json
from fastapi import APIRouter, WebSocket, WebSocketDisconnect

router = APIRouter()

connected_clients: list[WebSocket] = []


@router.websocket("/ws")
async def websocket_endpoint(ws: WebSocket):
    await ws.accept()
    connected_clients.append(ws)
    try:
        while True:
            await ws.receive_text()  # Keep connection alive
    except WebSocketDisconnect:
        connected_clients.remove(ws)


async def broadcast(event_type: str, data: dict):
    message = json.dumps({"type": event_type, "data": data})
    disconnected = []
    for ws in connected_clients:
        try:
            await ws.send_text(message)
        except Exception:
            disconnected.append(ws)
    for ws in disconnected:
        connected_clients.remove(ws)
```

**Step 2: Add background refresh tasks to main.py lifespan**

Add this to `main.py` inside the `lifespan` function, after Odoo authentication:

```python
import asyncio
from routers.ws import broadcast

async def refresh_loop():
    refresh = app_config.get_settings().get("refresh", {})
    odoo_interval = refresh.get("odoo_minutes", 5) * 60
    network_interval = refresh.get("network_minutes", 10) * 60
    ping_interval = refresh.get("ping_seconds", 60)

    last_odoo = 0
    last_network = 0
    last_ping = 0

    while True:
        now = asyncio.get_event_loop().time()

        if now - last_ping >= ping_interval:
            try:
                from modules.network_scanner import NetworkScanner
                scan_config = app_config.get_network_scan_config()
                scanner = NetworkScanner(scan_config.get("subnet", "192.168.1.0/24"))
                nodes = app_config.get_nodes()
                ips = [n["ip"] for n in nodes]
                statuses = await scanner.ping_all(ips)
                await broadcast("ping_update", statuses)
            except Exception:
                pass
            last_ping = now

        if now - last_odoo >= odoo_interval:
            try:
                await broadcast("odoo_refresh", {"trigger": "scheduled"})
            except Exception:
                pass
            last_odoo = now

        await asyncio.sleep(10)
```

Add to lifespan startup: `task = asyncio.create_task(refresh_loop())`
Add to lifespan shutdown: `task.cancel()`

**Step 3: Register ws router in main.py**

```python
from routers import network, tasks, calendar, services, ws
app.include_router(ws.router)
```

**Step 4: Commit**

```bash
git add backend/routers/ws.py backend/main.py
git commit -m "feat: add WebSocket for real-time updates with background refresh loop"
```

## Task 7: Frontend Project Scaffolding

**Files:**
- Create: `frontend/` (via Vite scaffold)
- Modify: `frontend/vite.config.ts`
- Modify: `frontend/tailwind.config.js`
- Create: `frontend/src/types/index.ts`

**Step 1: Scaffold React + TypeScript project with Vite**

Run:
```bash
cd /root/Dashboard
npm create vite@latest frontend -- --template react-ts
cd frontend
npm install
npm install -D tailwindcss @tailwindcss/vite
npm install d3 @types/d3 framer-motion
```

**Step 2: Configure Vite with Tailwind and API proxy**

Update `frontend/vite.config.ts`:

```typescript
import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import tailwindcss from "@tailwindcss/vite";

export default defineConfig({
  plugins: [react(), tailwindcss()],
  server: {
    host: "0.0.0.0",
    port: 5173,
    proxy: {
      "/api": "http://localhost:8000",
      "/ws": {
        target: "ws://localhost:8000",
        ws: true,
      },
    },
  },
});
```

**Step 3: Configure Tailwind for 4K**

Replace `frontend/src/index.css`:

```css
@import "tailwindcss";

@theme {
  --color-bg-primary: #0a0a0f;
  --color-bg-secondary: #12121a;
  --color-bg-card: #1a1a2e;
  --color-border: #2a2a3e;
  --color-text-primary: #e4e4e7;
  --color-text-secondary: #a1a1aa;
  --color-accent: #3b82f6;
  --color-success: #22c55e;
  --color-danger: #ef4444;
  --color-warning: #f59e0b;
}

html {
  font-size: 24px; /* Base for 4K — all rem values scale from here */
}

body {
  @apply bg-bg-primary text-text-primary;
  font-family: "Inter", system-ui, sans-serif;
  margin: 0;
  overflow: hidden;
  width: 3840px;
  height: 2160px;
}
```

**Step 4: Create TypeScript types**

```typescript
// frontend/src/types/index.ts

export interface NetworkNode {
  name: string;
  ip: string;
  username?: string;
  password?: string;
  public_url?: string;
  icon: string;
  status: "up" | "down" | "unknown";
  connections: string[];
  auto_discovered?: boolean;
  vendor?: string;
}

export interface TopologyData {
  nodes: NetworkNode[];
  scan_enabled: boolean;
}

export interface OdooTask {
  id: number;
  name: string;
  assigned: number[];
  priority: string;
  deadline: string | null;
  kanban_state: string;
}

export interface ProjectStages {
  [stageName: string]: OdooTask[];
}

export interface Project {
  id: number;
  name: string;
  color: number;
  stages: ProjectStages;
}

export interface TasksData {
  projects: Project[];
}

export interface CalendarEvent {
  id: number;
  name: string;
  start: string;
  stop: string;
  location?: string;
  description?: string;
}

export interface CalendarData {
  events: CalendarEvent[];
  date_from: string;
  date_to: string;
}

export interface DisplayConfig {
  resolution: string;
  rotation_interval_seconds: number;
  transition: string;
  theme: string;
}

export interface WSMessage {
  type: string;
  data: Record<string, unknown>;
}
```

**Step 5: Verify frontend builds**

Run: `cd /root/Dashboard/frontend && npm run build`
Expected: Build succeeds

**Step 6: Commit**

```bash
git add frontend/
git commit -m "feat: scaffold frontend with Vite, React, Tailwind 4K config, and TypeScript types"
```

**Files:**
- Create: `frontend/src/hooks/useOdooData.ts`
- Create: `frontend/src/hooks/useWebSocket.ts`
- Create: `frontend/src/hooks/useRotation.ts`

**Step 1: Create useOdooData hook**

```typescript
// frontend/src/hooks/useOdooData.ts
import { useState, useEffect, useCallback } from "react";
import type { TopologyData, TasksData, CalendarData, DisplayConfig } from "../types";

export function useTopology(refreshMs: number = 600_000) {
  const [data, setData] = useState<TopologyData | null>(null);
  const [error, setError] = useState<string | null>(null);

  const fetch_ = useCallback(async () => {
    try {
      const res = await fetch("/api/network/topology");
      if (!res.ok) throw new Error(`HTTP ${res.status}`);
      setData(await res.json());
      setError(null);
    } catch (e) {
      setError(e instanceof Error ? e.message : "Unknown error");
    }
  }, []);

  useEffect(() => {
    fetch_();
    const id = setInterval(fetch_, refreshMs);
    return () => clearInterval(id);
  }, [fetch_, refreshMs]);

  return { data, error, refetch: fetch_ };
}

export function useTasks(refreshMs: number = 300_000) {
  const [data, setData] = useState<TasksData | null>(null);
  const [error, setError] = useState<string | null>(null);

  const fetch_ = useCallback(async () => {
    try {
      const res = await fetch("/api/tasks/by-project");
      if (!res.ok) throw new Error(`HTTP ${res.status}`);
      setData(await res.json());
      setError(null);
    } catch (e) {
      setError(e instanceof Error ? e.message : "Unknown error");
    }
  }, []);

  useEffect(() => {
    fetch_();
    const id = setInterval(fetch_, refreshMs);
    return () => clearInterval(id);
  }, [fetch_, refreshMs]);

  return { data, error, refetch: fetch_ };
}

export function useCalendar(refreshMs: number = 300_000) {
  const [data, setData] = useState<CalendarData | null>(null);
  const [error, setError] = useState<string | null>(null);

  const fetch_ = useCallback(async () => {
    try {
      const res = await fetch("/api/calendar/events");
      if (!res.ok) throw new Error(`HTTP ${res.status}`);
      setData(await res.json());
      setError(null);
    } catch (e) {
      setError(e instanceof Error ? e.message : "Unknown error");
    }
  }, []);

  useEffect(() => {
    fetch_();
    const id = setInterval(fetch_, refreshMs);
    return () => clearInterval(id);
  }, [fetch_, refreshMs]);

  return { data, error, refetch: fetch_ };
}

export function useDisplayConfig() {
  const [config, setConfig] = useState<DisplayConfig | null>(null);

  useEffect(() => {
    fetch("/api/services/config")
      .then((r) => r.json())
      .then((d) => setConfig(d.display))
      .catch(() => {});
  }, []);

  return config;
}
```

**Step 2: Create useWebSocket hook**

```typescript
// frontend/src/hooks/useWebSocket.ts
import { useEffect, useRef, useCallback } from "react";
import type { WSMessage } from "../types";

export function useWebSocket(onMessage: (msg: WSMessage) => void) {
  const wsRef = useRef<WebSocket | null>(null);
  const reconnectTimeout = useRef<ReturnType<typeof setTimeout>>();

  const connect = useCallback(() => {
    const protocol = window.location.protocol === "https:" ? "wss:" : "ws:";
    const ws = new WebSocket(`${protocol}//${window.location.host}/ws`);

    ws.onmessage = (event) => {
      try {
        const msg: WSMessage = JSON.parse(event.data);
        onMessage(msg);
      } catch {}
    };

    ws.onclose = () => {
      reconnectTimeout.current = setTimeout(connect, 3000);
    };

    ws.onerror = () => ws.close();
    wsRef.current = ws;
  }, [onMessage]);

  useEffect(() => {
    connect();
    return () => {
      clearTimeout(reconnectTimeout.current);
      wsRef.current?.close();
    };
  }, [connect]);
}
```

**Step 3: Create useRotation hook**

```typescript

import { useState, useEffect } from "react";

export function useRotation(totalViews: number, intervalMs: number = 30_000) {
  const [activeView, setActiveView] = useState(0);

  useEffect(() => {
    const id = setInterval(() => {
      setActiveView((prev) => (prev + 1) % totalViews);
    }, intervalMs);
    return () => clearInterval(id);
  }, [totalViews, intervalMs]);

  return activeView;
}
```

**Step 4: Commit**

```bash
git add frontend/src/hooks/
git commit -m "feat: add React hooks for data fetching, WebSocket, and view rotation"
```

## Task 9: Layout Components (Header + ViewRotator)

**Files:**
- Create: `frontend/src/components/Layout/Header.tsx`
- Create: `frontend/src/components/Layout/ViewRotator.tsx`

**Step 1: Create Header component**

```typescript
// frontend/src/components/Layout/Header.tsx
import { useState, useEffect } from "react";

interface HeaderProps {
  viewName: string;
  connected: boolean;
}

export function Header({ viewName, connected }: HeaderProps) {
  const [time, setTime] = useState(new Date());

  useEffect(() => {
    const id = setInterval(() => setTime(new Date()), 1000);

## Task 10: Network Topology View (D3.js Graph)

**Files:**
- Create: `frontend/src/components/Topology/NodeCard.tsx`
- Create: `frontend/src/components/Topology/NetworkGraph.tsx`

**Step 1: Create NodeCard component**

This is the tooltip/card that shows node details when hovering. For the TV, nodes show info directly.

```typescript
// frontend/src/components/Topology/NodeCard.tsx
import { useState } from "react";
import type { NetworkNode } from "../../types";

const ICON_MAP: Record<string, string> = {
  router: "🌐",
  server: "🖥️",
  switch: "🔀",
  ap: "📡",
  pc: "💻",
  nas: "💾",
  device: "📱",
};

interface NodeCardProps {
  node: NetworkNode;
  x: number;
  y: number;
}

export function NodeCard({ node, x, y }: NodeCardProps) {
  const [showPassword, setShowPassword] = useState(false);

  const statusColor =
    node.status === "up" ? "bg-success" : node.status === "down" ? "bg-danger" : "bg-warning";

  return (
    <foreignObject x={x - 120} y={y - 80} width={240} height={180}>
      <div
        className="bg-bg-card border border-border rounded-xl p-4 flex flex-col items-center gap-1 shadow-lg cursor-pointer select-none"
        onClick={() => setShowPassword((prev) => !prev)}
      >
        <span className="text-3xl">{ICON_MAP[node.icon] || "📦"}</span>
        <span className="text-base font-bold text-text-primary truncate w-full text-center">
          {node.name}
        </span>
        <span className="text-sm text-text-secondary font-mono">{node.ip}</span>
        {node.username && (
          <span className="text-sm text-text-secondary">
            {node.username} / {showPassword ? node.password : "••••"}
          </span>
        )}
        {node.public_url && (
          <span className="text-xs text-accent truncate w-full text-center">
            {node.public_url}
          </span>
        )}
        <div className="flex items-center gap-2 mt-1">
          <span className={`w-3 h-3 rounded-full ${statusColor}`} />
          <span className="text-xs text-text-secondary">
            {node.status === "up" ? "Online" : node.status === "down" ? "Offline" : "Unknown"}
          </span>
        </div>
      </div>
    </foreignObject>
  );
}
```

**Step 2: Create NetworkGraph component**

```typescript
// frontend/src/components/Topology/NetworkGraph.tsx
import { useEffect, useRef } from "react";
import * as d3 from "d3";
import { NodeCard } from "./NodeCard";
import type { NetworkNode } from "../../types";

    }));

    const nodeMap = new Map(simNodes.map((n) => [n.data.name, n]));

    const simLinks: SimLink[] = [];

        }
      }
    }

    nodesRef.current = simNodes;
    linksRef.current = simLinks;

    const sim = d3

          .attr("stroke", "#2a2a3e")
          .attr("stroke-width", 3);
      });

    simRef.current = sim;

    return () => {
      sim.stop();
    };
  }, [nodes]);

  const onlineCount = nodes.filter((n) => n.status === "up").length;
  const offlineCount = nodes.filter((n) => n.status === "down").length;

  return (

        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
    }
}
```

**Step 3: Create docker-compose.yaml**

```yaml
# docker-compose.yaml
services:
  backend:
    build: ./backend
    restart: always
    volumes:
      - ./backend/config:/app/config
    networks:
      - dashboard
    # host network needed for nmap and ping to work on local network
    network_mode: host

  frontend:
    build: ./frontend
    restart: always
    ports:
      - "80:80"
    depends_on:
      - backend
    networks:
      - dashboard

networks:
  dashboard:
    driver: bridge
```

Note: The backend uses `network_mode: host` so nmap and ping can access the local network. The frontend connects to backend via Docker network. This needs adjustment — we'll use a single network with host mode on backend:

```yaml
# docker-compose.yaml (corrected)
services:
  backend:
    build: ./backend
    restart: always
    network_mode: host
    volumes:
      - ./backend/config:/app/config

  frontend:
    build: ./frontend
    restart: always
    ports:
      - "80:80"
    extra_hosts:
      - "backend:host-gateway"
```

**Step 4: Create .gitignore**

```gitignore
# Python
__pycache__/
*.pyc
.venv/
venv/
*.egg-info/

# Node
node_modules/
dist/

# IDE
.vscode/
.idea/

# OS
.DS_Store

# Config with secrets (user should copy from example)
# backend/config/settings.yaml
# backend/config/services.yaml
```

**Step 5: Commit**

```bash
git add docker-compose.yaml backend/Dockerfile frontend/Dockerfile frontend/nginx.conf .gitignore
git commit -m "feat: add Docker Compose setup with backend, frontend/nginx, and gitignore"
```

---

## Task 15: End-to-End Verification

**Step 1: Verify backend starts and serves API**

```bash
cd /root/Dashboard/backend
pip install -r requirements.txt
python -m uvicorn main:app --host 0.0.0.0 --port 8000 &
sleep 2
curl http://localhost:8000/api/health
curl http://localhost:8000/api/services/config
kill %1
```

Expected: Health endpoint returns JSON. Config endpoint returns display settings.

**Step 2: Verify frontend builds**

```bash
cd /root/Dashboard/frontend
npm install
npm run build
```

Expected: Build succeeds, `dist/` directory created.

**Step 3: Verify Docker Compose builds**

```bash
cd /root/Dashboard
docker compose build
```

Expected: Both images build successfully.

**Step 4: Final commit with any fixes**

```bash
git add -A
git status
# Only commit if there are changes
git commit -m "chore: final adjustments from end-to-end verification"
```
