# Promotes the current landing page to PRODUCTION: the `open-design-landing`
# Cloudflare Pages project, served at open-design.ai. This is the ONLY
# workflow that names the production project, and it is manual-only
# (workflow_dispatch) — a merge to `main` can never reach production on its
# own; it only updates the staging project (staging.open-design.ai) via
# `landing-page-staging`. Gate this further by configuring required reviewers
# on the GitHub `production` environment (Settings → Environments).
#
# The build is identical to staging/CI, so what you reviewed on
# staging.open-design.ai is what ships.
