# Headless Chromium exposing a CDP endpoint for Hermes browser tools.
# Loopback only; browser.cdp_url in ~/.hermes/config.yaml points at it.
# Ungoogled-chromium (already in desktop-packages-light.nix), no ad-block
# extension so behavior stays stock; dedicated user-data-dir so this
# instance never touches kyle's browsing profile.
