Intent-aware visual verification for coding agents: the agent declares what a UI change should affect, and SnapDiff diffs the page against a baseline and flags anything that changed outside that intent for review or rollback — local screenshot capture via Playwright.
Point your coding agent at a URL and get a real-browser QA audit: broken signup/login/checkout flows, JS console errors, missing analytics, consent + security headers, mobile tap targets, and accessibility — returned as machine-verified findings graded A–F. Free 60-second audit, no signup.

snapdiff_verify_ui_change
Checks whether a visual change matches the agent's stated intent. Returns `verdict` (`pass` / `expected_change_detected` / `unexpected_regression` / `no_change_detected` / `needs_human_review`) and a `next_action`. Requires a project + baseline. **Use this in the verification loop.
