# Git(tea) Actions workflow: Build and publish standalone binaries **plus** bundled `static/` assets
# ────────────────────────────────────────────────────────────────────
#  ✧  Builds the Go‑based WoL server for four targets **and** packt das Verzeichnis
#      `static` zusammen mit der Binary, sodass es relativ zur ausführbaren Datei
#      liegt (wichtig für die eingebauten Bootstrap‑Assets & favicon).
#
#       • linux/amd64    → wol-server-linux-amd64.tar.gz
#       • linux/arm64    → wol-server-linux-arm64.tar.gz
#       • linux/arm/v7   → wol-server-linux-armv7.tar.gz
#       • windows/amd64  → wol-server-windows-amd64.zip
#
#  ✧  Artefakte landen im Workflow und – bei Tag‑Push (vX.Y.Z) – als Release‑Assets.
#
#  Secrets/variables:
#    GITEA_TOKEN – optional, falls default token keine Release‑Rechte hat.
