# Exporta o Rusty's Mini Golf (Sleeping Colossus, BSD-2-Clause; github.com/SleepingColossus/rustys-mini-golf, commit
# 2fd37d6) para a web com o Godot 4.4.1 oficial (o projeto e do 4.1; usamos o mais proximo que temos): renderer
# Compatibility (o do proprio projeto), SEM threads (modelo web_nothreads_release), sem PWA.
#
# Mudancas no jogo (rustys-mini-golf/patch.py): saem os botoes de redes sociais do menu (links para fora e logos de
# marcas), o icone padrao do Godot e a pasta de sons brutos sem origem registrada (Assets/Audacity, ja sem uso no jogo); a
# fonte Cakecafe (sem licenca de redistribuicao) vira a Lilita One (SIL OFL, google/fonts); e os 9 efeitos sonoros
# (.ogg do autor, sem credito de origem) sao trocados pelos nossos, sintetizados por rustys-mini-golf/sounds.py (dominio
# publico) com os mesmos nomes de arquivo. A musica e todo o resto da arte sao do autor e ficam como estao.
#
#   src/FredGames.Bundler/Builds/build-rustys-mini-golf.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/rustys-mini-golf-2fd37d6/{web/,rustys-mini-golf-2fd37d6.tar.gz}, que o bundle.yaml do jogo
# confere pelo SHA-256. O tar.gz e o fonte do jogo ja com as mudancas acima e sai igual a cada execucao.
