# Deploy the WattHound demo. NO GitHub involved.
#
# Source of truth : ./index.html  (committed to Gitea, built by Coolify)
# Git host        : gitea.sculpt.co.nz/macjones/watthound-demo  (public, Mac's own server)
# Runtime         : Coolify app "watthound-demo-gitea" -> nginx:alpine, FQDN
#                   https://watthound-demo.sculpt7.com
#
# Flow: commit index.html -> push to Gitea -> trigger Coolify deploy -> verify.
#
# Usage:  ./deploy.sh                 # commits & pushes ./index.html, then deploys
#         ./deploy.sh /path/to/new/index.html   # copies that file in first
#
# Requires: COOLIFY_API_TOKEN + COOLIFY_URL in the myPKA .env (never printed).
#           git push access to the gitea remote (already configured / keychain).
