# Git-pull-based deploy for Erik. Replaces the ad-hoc per-file `cat file | ssh`
# uploads used on 2026-07-16, which twice missed files that server.js actually
# requires (src/backend/config.js, src/backend/services/smtp.js) because
# uploading was a manual, easy-to-forget step instead of a single `git pull`.
#
# Run this ON Erik, from /opt/peercortex-app. Deliberately manual (not wired
# to a Gitea Action) -- Erik hosts many unrelated production services and
# main can contain code that hasn't been live-tested yet (see project memory).
#
# Usage: ./deploy-from-git.sh [branch]   (default: main)
