# Exporta o Stomper (Diego Escalante, GitHub Game Off 2022; MIT) para a web com o Godot 3.5.3 oficial:
# modelo webassembly_release (sem threads: nao precisa de SharedArrayBuffer nem de COOP/COEP), sem PWA.
# O jogo roda como o autor publicou; o repositorio nao traz export_presets.cfg (esta no .gitignore), entao
# o nosso fica ao lado deste script. Tres mudancas no projeto, todas feitas aqui:
#   1. Fonts/StylishRegularFont.ttf (10,8 MB, coreano inteiro) vira um subconjunto com Basic Latin, Latin-1
#      e pontuacao geral (fonttools; a tabela name e a licenca OFL seguem intactas; a fonte Stylish da
#      AsiaSoft e OFL 1.1 sem nome reservado, ver google/fonts ofl/stylish/OFL.txt).
#   2. Audio/music.wav.import: compress/mode 0 -> 1 (IMA-ADPCM), a musica cai de 10,5 MB para ~2,7 MB;
#      o laco (loop_mode=2) continua o mesmo.
#   3. O export deixa de fora os arquivos de autoria (.aseprite, .aup, .cpt, Audio/music_data/).
#
#   src/FredGames.Bundler/Builds/build-stomper.sh
#
# Saida: artifacts/build/stomper-0444d1a/{web/,stomper-0444d1a.tar.gz}, que o bundle.yaml do jogo confere
# pelo SHA-256. O tar.gz e o repositorio do commit sem Audio/music_data/ (dados temporarios do Audacity, 76 MB)
# e sai igual a cada execucao.
