# CC BY 4.0, sons CC0 e CC BY 3.0, fonte Press Start 2P OFL; creditos de terceiros no GameInfo.tres/tela Sobre) para a web
# com o Godot 4.7.2 oficial: renderer Compatibility, SEM threads (modelo web_nothreads_release: nao precisa de
# SharedArrayBuffer nem dos cabecalhos COOP/COEP), sem PWA. O export_presets.cfg e nosso, ao lado deste script (o do
# repositorio tem 17 presets para outras plataformas e lojas). Mudancas no projeto, feitas por este script (a funcao
# customize, abaixo, e circlerc/adapt.py): saem os icones de redes sociais (Art/Icons) e o menu de links sociais, a tela
# Sobre nao abre links e o id do Game Jolt sai; o projeto vai para o renderer Compatibility. As integracoes com
# Newgrounds e Game Jolt so ligam com flags de exportacao que o nosso preset nao tem (ver adapt.py).
#
#   src/FredGames.Bundler/Builds/build-circlerc.sh
#
# O editor (macOS universal) e os modelos de exportacao vem do release 4.7.2-stable do GitHub, conferidos pelo
# SHA-256 e ficam em artifacts/tools/godot-4.7.2, 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/circlerc-6e23e83/{web/,circlerc-6e23e83.tar.gz}, que o bundle.yaml do jogo confere
# pelo SHA-256. O tar.gz e o fonte publicado (o projeto no commit pinado ja com as mudancas acima) e sai igual a
# cada execucao.
