+Use `--delay` as a real CLI option (outside the text argument):
+
+```bash
+agent-browser type @e2 "iphone" --delay 120
+agent-browser keyboard type "iphone" --delay 120

 `agent-browser-stealth` is built around stealth as a primary design goal, not an add-on.
 Stealth is **always on** with no flag needed. Every browser session automatically applies anti-detection countermeasures:
+Legacy protocol field `launch.stealth` is accepted for compatibility but ignored.
 
 - **Uses Chrome channel for Chromium launches** -- local Chromium sessions are launched through Playwright's `chrome` channel for a genuine Chrome fingerprint
 
 - Removes `navigator.webdriver` automation indicator
 - Disables Chromium's `AutomationControlled` blink feature
 - Replaces "HeadlessChrome" in User-Agent and userAgentData (including CDP-level override)
+- Preserves explicit custom User-Agent from `--user-agent` / `launch({ userAgent })`
 - Uses ANGLE rendering instead of SwiftShader to avoid GPU fingerprinting
 - Adds realistic `navigator.plugins` and `navigator.mimeTypes` (passes `instanceof` checks)
 - Patches `window.chrome.runtime` to match real Chrome
