headless-fallback

Use when a static fetch returns nothing useful and the page needs a real browser. Covers `--browser-mode auto|always|never`, external CDP via `--browser-endpoint`, symptoms of JS-only pages and WAF blocks, and the performance cost.

# Headless fallback

Some pages are unscrapable without a real browser — SPA shells, infinite
scroll, Cloudflare interstitials, JS-rendered article bodies. Kreuzcrawl
ships with an optional headless-Chrome backend driven by chromiumoxide.

## Modes

```text
--browser-mode auto    # default — try static first, fall back to browser on JS/WAF
--browser-mode always  # skip static, go straight to browser
--browser-mode never   # static only, fail closed
```
