+# release.sh — publish a new version of the Thunderbird add-on to Gitea
+# and update updates.json so installed clients auto-update.
+#
+# Prereqs:
+#   - manifest.json "version" already bumped to the new version
+#   - templates-reply-hotel.xpi rebuilt for that version, WITHOUT defaults.local.json
+#     (the token must not ship in a public release; updates don't need defaults anyway)
+#   - GITEA_TOKEN exported (a Gitea token with repo write access)
+#
+# Usage:  GITEA_TOKEN=xxxx ./release.sh
