# the System One base's own Python (the venv the image installs for that base, which carries
# browser-use and the MCP SDK) and on the Chromium installed beside it; outside the image, any
# python3 with `systemone-harness[browser]` and a Chrome on the machine will do.
#
# An MCP stdio server gets a restricted environment from the SDK, so nothing the image exported
# reaches this script, and a hosted sandbox's HOME is made per session, so a home-relative venv
# never matches one the image installed. The interpreter and the browsers are therefore found
# here, by name: SYSTEMONE_PYTHON if the host set it for the server, then the known venv paths;
# PLAYWRIGHT_BROWSERS_PATH if set, then the known browser roots that hold a chromium-* directory.
