# don't show a real maintainer's avatar/email — sally is a stock admin user
# kept on the stable install for marketing screenshots.

# admin auth cache so other Playwright tests keep using their normal admin

# Pre-flight: stable docker WP is running, premium plugin is installed
# (active or inactive — script handles both), and the sally/sally admin
# user exists on stable.
