## Core Features

### 1. Intelligent Web Scraper

**Capabilities:**
- Automatically discovers cy pres pages using pattern matching
- Falls back to site crawling if patterns don't match
- Supports both static HTML and JavaScript-rendered sites
- Respects robots.txt and rate limits
- Extracts organization details (name, logo, mission, cy pres statement)
- Auto-categorizes using NLP (Naive Bayes classifier)
- Batch processing with configurable concurrency

**Example Usage:**
```bash
npm run scrape:test  # Test with 3 sample organizations
npm run scrape       # Production scrape of 50+ organizations
```
