#!/usr/bin/env bash
# Publish a built static site to Codeberg Pages.
#
# One codebase, three real domains (atproto.nl/.be/.eu). SITE_SCOPE picks which one this run
# builds and which Codeberg repo it pushes to; each domain is a standalone Codeberg Pages repo
# with its own `pages` branch. Home base stays Tangled; Codeberg is only the delivery layer.
#
# The custom domain is claimed by dist/.domains, which astro.config.mjs writes from the scope at
# build time -- so this script never has to know the hostname, only which remote to push.
#
# Usage:
#   SITE_SCOPE=nl bash scripts/deploy-codeberg.sh   # -> remote `codeberg`     (atproto.nl)
#   SITE_SCOPE=be bash scripts/deploy-codeberg.sh   # -> remote `codeberg-be`  (atproto.be)
#   SITE_SCOPE=eu bash scripts/deploy-codeberg.sh   # -> remote `codeberg-eu`  (atproto.eu)
# Deploy all three:  for s in nl be eu; do SITE_SCOPE=$s bash scripts/deploy-codeberg.sh; done
#
# Prereqs (per scope): a Codeberg remote over ssh (auth via ~/.ssh/id_ed25519_codeberg), e.g.
#   git remote add codeberg-be codeberg.org:gxjansen/atprotobe-website.git
#   git remote add codeberg-eu codeberg.org:gxjansen/atprotoeu-website.git
# and rsync available. The `_git-pages-repository.<domain>` TXT record must point at the same repo.
