+# Engineering & Scraping Guidelines
+
+## 1. Git Commit & Repository Hygiene
+- **Conventional Commits:** Write clear, concise commit messages prefixed with standard types (e.g., `feat:`, `fix:`, `refactor:`, `docs:`).
+- **Exclude Transient Artifacts:** Never stage or commit generated debug files (e.g., `src/*.html`, `src/*.png`, large logs) to version control. Always maintain `.gitignore` to keep git packs lean and prevent remote unpacker errors on Gitea/GitHub.
+
+## 2. Web Scraping & DOM Inspection Strategy
+- **Rendered DOM Dumping for Debugging:** When debugging extraction failures on dynamic or anti-bot protected pages:
+  - Capture the post-render HTML via `await page.content()` and save it to `src/hotel-debug.html`.
+  - Capture a synchronized screenshot (`src/hotel-debug.png`).
+  - Inspect the raw rendered DOM to verify if the page was served as standard SSR, an A/B test SPA variant, or intercepted by a challenge (e.g. AWS WAF).
+- **Multi-Tier Extraction Hierarchy:** Always implement fallbacks in this order:
+  1. **Deep JSON-LD Parsing:** Traverse all `<script type="application/ld+json">` tags, including `@graph` arrays and varied accommodation schemas (`Hotel`, `Resort`, `Apartment`, `Hostel`, `LodgingBusiness`, etc.).
+  2. **DOM Selectors:** Fallback to standard test IDs, classes, and element hierarchy (`data-testid`, header titles, score components).
+  3. **Meta Tags:** Fallback to OpenGraph and Twitter meta tags (`og:title`, `og:image`, `og:description`).
+  4. **URL Slug Extraction:** As an ultimate safety net, derive clean human-readable names from the URL path if the HTML body was obstructed.
+- **Anti-Bot & WAF Handling:**
+  - Sanitize input URLs by stripping transient tokens (`chal_t`, `force_referer`, session IDs).
+  - Emulate full browser properties (`window.chrome`, `navigator.plugins`, `navigator.languages`).
+  - Actively detect WAF challenge interstitial pages and wait for client-side JavaScript token computation and automatic redirection before evaluating the DOM.

+# 📍 Travel Dashboard & Hotel Ranking
+
+A Next.js web application for comparing hotels, planning travel stops, tracking historical Booking.com prices (including Genius discounts), and rating accommodations with friends using German school grades (1–6).
+
+---
+
+## 🌟 Key Features
+
+- **Trip Management & Hotel Assignment:** Organize hotels across multiple trips or unassigned stops. When adding a hotel, you can directly choose which trip to assign it to.
+- **Automated Metadata & Price Scraping:** Adding a Booking.com URL automatically triggers a background BullMQ job that fetches the hotel name, star rating, address, hero image, room size, and prices.
+- **On-Demand Stammdaten Refresh:** Each hotel card features a **"🔄 Stammdaten"** button to perform a fast re-scan of metadata and prices on demand.
+- **AI Review Summaries:** Integrates with local LLMs (via Ollama/n8n) to summarize up to 80+ guest reviews into categorized highlights (Positive, Neutral, Negative, Bathroom inspection).
+- **Bathroom Photos & Google Maps Inspection:** Upload manual bathroom photos or inspect Google Maps imagery to assess room cleanliness.
+- **Price History & Genius Tracking:** Records price changes over time with automatic detection of Genius discount badges (-10%).
+- **Sights & Attractions:** Manage points of interest and calculate distances/durations from each hotel.
+
+---
+
+## 🏗️ Architecture & Stack
+
+- **Frontend & API:** Next.js (App Router, TypeScript, React)
+- **Database:** PostgreSQL
+- **Task Queue:** BullMQ / Redis (shared with `scraper-service`)
+- **Containerization:** Docker & Docker Compose
+
+---
+
+## 🚀 Getting Started
+
+### Prerequisites
+- Docker & Docker Compose
+- Running PostgreSQL & Redis instances
+
+### Environment Variables (`.env`)
+```env
+DATABASE_URL=postgresql://user:password@host:5432/travel_db
+REDIS_HOST=172.17.0.1
+REDIS_PORT=6379
+APP_WEBHOOK_URL=https://n8n.your-domain.de/webhook/scrape-reviews
+```
+
+### Running with Docker Compose
+```bash
+docker compose up -d --build
+```
+The app will be accessible at `http://localhost:3002`.
+
+---
+
+## 📡 API Endpoints
+
+- `GET /api/hotels` — List all hotels, current prices, and ratings.
+- `POST /api/hotels` — Create a new hotel and enqueue background metadata scraping.
+- `PATCH /api/hotels/[id]` — Update hotel properties (e.g. active/parked status).
+- `POST /api/hotels/[id]/scan` — Trigger on-demand scraping:
+  - `?mode=stammdaten` (or `mode=quick`): Fast scan for name, address, rating, price, and images.
+  - Default: Full review scan with n8n/LLM review summary.
+  - `?debug=true`: Generates raw HTML and screenshot dumps in `scraper-service`.
+- `POST /api/jobs/trigger-daily-check` — Enqueue batch price updates for all active hotels.
+- `POST /api/webhooks/scraper` — Webhook receiver for scraped metadata from `scraper-service`.
+- `GET /api/trips` / `POST /api/trips` — Manage trip entities.
+- `GET /api/attractions` / `POST /api/attractions` — Manage central sights and hotel assignments.
