Currently (I think) theres only one way to take a screenshot (via events):

screenshot_event = browser_session.event_bus.dispatch(ScreenshotEvent(full_page=True))
await screenshot_event 
screenshot_b64 = await screenshot_event.event_result()

This is much easier:

 screenshot_data = await browser_session.take_screenshot(full_page=True)

Also I need this for demos plz.

Summary by cubic

Adds a simple screenshot API to BrowserSession, replacing the event‑bus flow. Supports full-page, region, and element captures, with optional file save and format control.

• New Features
  • BrowserSession.take_screenshot(path=None, full_page=False, format='png', quality=None, clip=None) returns bytes; supports png/jpeg/webp, JPEG quality, optional clip, and saving to disk.
  • BrowserSession.screenshot_element(selector, path=None, format='png', quality=None) captures a CSS-selected element by auto-computing bounds.
  • CI test verifies viewport and element screenshots return data.
