# Local deploy — the fallback while Gitea Actions is unavailable.
#
# Gitea Actions needs `[actions] ENABLED = true` in app.ini and a registered
# act_runner. The instance is jointly administered, so both depend on a second
# administrator (AGENTS.md Q23). Until that lands, this script is how the site
# ships.
#
# It performs EXACTLY what .gitea/workflows/deploy.yml performs: the same guard,
# the same three sync passes in the same order with the same cache headers, and
# the same invalidation. At this scale the pipeline changes only how a deploy is
# TRIGGERED, not what it does — so this is a fallback, not a lesser path. Any
# change to one must be made to the other.
#
# Required environment (values are in AGENTS.md §7 — deliberately not restated
# here; §7 is the single source of truth for operational facts):
#
#   AWS_REGION  S3_BUCKET  CLOUDFRONT_DISTRIBUTION_ID  INTAKE_ENDPOINT
#
# Credentials: use the scoped deploy user. AGENTS.md Q22 records that it does
# NOT yet exist. NEVER run this as user/pouya — see AGENTS.md §10.
