/**
 * Weavetab — tools/screenshot.ts
 * browser_screenshot: Capture the current tab as a base64 PNG using Page.captureScreenshot.
 *
 * Use this tool when you need pixel-level vision of the page — e.g. to verify a visual
 * result, read text in images, inspect canvas content, or confirm UI state that the DOM
 * tree cannot describe. Returns a data URL the AI can interpret visually by default.
 *
 * Do NOT use this as a replacement for browser_map — use browser_map first to interact
 * with elements. Use browser_screenshot only when visual confirmation is needed.
