# Exporta o Magickal Powers (eddex, Kenney Jam 2025; codigo MIT, arte CC0 de Kenney e Kay Lousberg, musica de
# Miguel Herrero CC BY-SA 3.0, github.com/eddex/magickal-powers) para a web com o Godot 4.4.1 oficial (a versao
# do projeto, "4.4"): renderer Compatibility, SEM threads (modelo web_nothreads_release: nao precisa de
# SharedArrayBuffer nem dos cabecalhos COOP/COEP), sem PWA. O projeto do autor nao muda; so acrescentamos o
# export_presets.cfg ao lado deste script (o do repositorio nao serve para a nossa pagina).
#
#   src/FredGames.Bundler/Builds/build-magickal-powers.sh
#
# O editor (macOS universal) e os modelos de exportacao vem do release 4.4.1-stable do GitHub, conferidos pelo
# SHA-256 (os mesmos arquivos do SHA512-SUMS.txt do release) e ficam em artifacts/tools/godot-4.4.1, instalados
# sob lockf (outros scripts podem estar instalando ao mesmo tempo). O editor roda com HOME dentro da pasta de
# saida (configuracao e modelo isolados).
#
# Saida: artifacts/build/magickal-powers-7794941/{web/,magickal-powers-7794941.tar.gz}, que o bundle.yaml do
# jogo confere pelo SHA-256. O tar.gz e o fonte do jogo no commit pinado e sai igual a cada execucao.
