```bash
# Extract from file
html2json examples/hn.html --spec examples/hn.json

# Extract from stdin (pipe from curl)
curl -s https://news.ycombinator.com/ | html2json --spec examples/hn.json

# Extract from stdin (pipe from cat)
cat examples/hn.html | html2json --spec examples/hn.json

# Check output matches expected JSON (useful for testing/CI)
html2json examples/hn.html --spec examples/hn.json --check expected.json
```
