# Exporta o Mini Mobile Network Operator (Hendrik Wilka, Ludum Dare 59, BSD-3-Clause; github.com/hwilka/Mini-Mobile-Network-Operator)
# para a web com o Godot 4.7.2 oficial (o projeto e do Godot 4.6; 4.7.2 e a versao mais proxima que temos): renderer Compatibility,
# SEM threads (modelo web_nothreads_release), sem PWA. O projeto do autor nao muda; so acrescentamos o export_presets.cfg.
#
#   src/FredGames.Bundler/Builds/build-mini-mobile-network-operator.sh
#
# O editor (macOS universal) e os modelos de exportacao vem do release 4.7.2-stable do GitHub, conferidos pelo
# SHA-256 (os mesmos arquivos do SHA512-SUMS.txt do release) 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/mini-mobile-network-operator-3325ba3/{web/,mini-mobile-network-operator-3325ba3.tar.gz}, que o bundle.yaml do jogo confere pelo
# SHA-256. O fonte (tar.gz) sai igual a cada execucao.
