# Exporta o Aqua Journey (Yeldham, Godot Community Game Jam de junho de 2018; codigo AGPL-3.0, arte CC BY-SA 4.0,
# musica "Running Waters" de Jason Shaw CC BY, demais sons CC0; codeberg.org/Yeldham/aqua-journey) para a web
# com o Godot 3.5.3 oficial: modelo webassembly_release (sem threads: nao precisa de SharedArrayBuffer nem de
# COOP/COEP), sem PWA. O projeto e do Godot 3.0 (config_version 3): o editor 3.5 o reimporta e converte os
# recursos sozinho na primeira passada, sem mudar nada no jogo. O repositorio nao traz export_presets.cfg; o
# nosso fica ao lado deste script. Unica mudanca no projeto, feita aqui e visivel no fonte publicado: o botao
# "Exit" do menu (get_tree().quit(), que apaga a pagina no navegador) fica escondido.
#
#   src/FredGames.Bundler/Builds/build-aqua-journey.sh
#
# Saida: artifacts/build/aqua-journey-dd363c4/{web/,aqua-journey-dd363c4.tar.gz}, que o bundle.yaml do jogo confere
# pelo SHA-256. O tar.gz e o repositorio do commit (AGPL: o fonte exato do que e servido) e sai igual a cada execucao.
