# Exporta Office Lunch Mystery (no repositorio, The No Good Sandwich Thief) (Wandering Door Games, codeberg.org/Wandering-Door-Games/The-No-Good-Sandwich-Thief; codigo AGPL-3.0-or-later, arte original
# CC BY-SA 4.0, creditos de terceiros no THIRD-PARTY.md) para a web com o Godot 4.5.1 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 nao
# serve para a web). Mudancas no projeto, feitas por este script (a funcao customize, abaixo, e os patches em
# Builds/office-lunch-mystery/): a pasta assets/branding sai (o README reserva o nome do estudio, icones e logos), o splash
# do estudio fica em branco, o projeto vai para o renderer Compatibility e fica sem icone de projeto.
#
#   src/FredGames.Bundler/Builds/build-office-lunch-mystery.sh
#
# As imagens do repositorio estao no Git LFS (o tarball do Codeberg traz so os ponteiros): o script baixa cada
# objeto do endpoint de midia no commit pinado e confere o sha256 do ponteiro.
#
# O editor (macOS universal) e os modelos de exportacao vem do release 4.5.1-stable do GitHub, conferidos pelo
# SHA-256 e ficam em artifacts/tools/godot-4.5.1, 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/office-lunch-mystery-ebc1709/{web/,office-lunch-mystery-ebc1709.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 as imagens
# do LFS) e sai igual a cada execucao.
