# Exporta o Candy Wrapper (Harmony Honey Monroe; MIT; arte, musica e sons do proprio autor) para a web com o
# Godot 4.4.1 oficial (a versao do README): renderer Compatibility (o padrao do Godot 4 na web), SEM threads
# (modelo web_nothreads_release: nao precisa de SharedArrayBuffer nem dos cabecalhos COOP/COEP), sem PWA. O
# projeto do autor nao muda; so trocamos o export_presets.cfg (o do repositorio exporta para Linux, Windows e
# macOS e nao tem preset web) pelo nosso, ao lado deste script.
#
#   src/FredGames.Bundler/Builds/build-candy-wrapper.sh
#
# Saida: artifacts/build/candy-wrapper-de75907/{web/,candy-wrapper-de75907.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.
