name: Visual Regression Dispatch

# Dispatches visual regression processing to twenty-factory after CI completes.
# Runs in the context of the base repo (not the fork) so it has access to secrets,
# making it work for external contributor PRs.
#
# All paths trigger the same twenty-factory workflow (post-visual-regression-comment.yaml)
# via workflow_dispatch, passing the project as an input. twenty-factory routes to the
# correct Argos project based on it.
