# Exporta o Godog (Team Godog; corrida de trenó 3D feita em 2 dias para a Nordic Game Jam 2023, Godot 4.0; scripts e cenas
# MIT, modelos, texturas, sons e musica da propria equipe, CC BY 4.0; github.com/team-godog/NGJ2023_Godog) para a web com o
# Godot 4.4.1 oficial (o mais proximo do 4.0 em artifacts/tools; o projeto abre sem mudanca de conteudo): renderer
# Compatibility (o projeto pede Forward+), SEM threads (modelo web_nothreads_release), sem PWA. Mudancas (godog/web.patch):
# renderer gl_compatibility, janela em modo normal (era tela cheia), botoes Quit do menu escondidos e a fonte do botao
# "Play" trocada: a EthnicABC (Liuna Virardi, licenca "Creative Commons" sem variante) sai e entra a Lilita One (SIL OFL,
# google/fonts, commit e SHA-256 abaixo, com o OFL.txt ao lado). Ficam fora da arvore de build tres arquivos soltos de
# IntroSlides (.tmp e copias sem extensao).
#
#   src/FredGames.Bundler/Builds/build-godog.sh
#
# O editor (macOS universal) e os modelos de exportacao vem do release 4.4.1-stable do GitHub, conferidos pelo
# SHA-256 e ficam em artifacts/tools/godot-4.4.1, instalados sob lockf. O editor roda com HOME dentro da pasta de saida.
#
# Saida: artifacts/build/godog-212feb1/web/, que o bundle.yaml do jogo confere pelo SHA-256. O codigo e as licencas dos
# assets nao exigem o fonte no bucket: o script fixa o commit e o SHA-256 do tarball.
