name: Browser smoke

# Headless page-load smoke: boots the real server.py (agent-free) and loads the
# key pages in Chromium, failing on any console error or uncaught JS exception.
# This catches the runtime-JS brick class (const-reassign, function/window
# collision) that `node --check`, ESLint, and the mocked pytest suite cannot
# see — they only manifest when a real browser executes the page.
#
# No secrets, no credentials: the server boots agent-free and the smoke script
# strips every *_API_KEY from the environment before launch.
