Browser automation and testing using Vercel's agent-browser CLI with ref-based element targeting

Drive a REAL browser and native apps the way a user would — not fetch raw HTML — through the persistent `browse` CLI: one long-lived headless Chromium (plus iOS, Android, and macOS apps via accessibility APIs) where goto, snapshot, click, fill, JavaScript, and screenshot share session state at ~100ms/command and interaction rides stable @eN refs, not brittle selectors. Use when verifying, navigating, or automating live web or app behavior beyond what code-reading or a raw fetch reveals.

Implements security headers and Content Security Policy with safe rollout strategy (report-only → enforce), testing, and compatibility checks. Use for "security headers", "CSP", "HTTP headers", or "XSS protection".
