# Gera o arkaway.pyxapp do Arkaway (son-link, GPL-3.0) a partir do commit dbffac5 do repositorio, com um patch
# nosso (publicado junto do fonte):
#   arkaway/save-scores-in-browser.patch  as melhores pontuacoes iam para ./scores.json (que nao persiste na
#                                         web); agora vao para /saves/arkaway/, a pasta que o play/pyxel.html
#                                         guarda no IndexedDB, quando ela existe (no desktop nada muda); nessa
#                                         pasta a tecla Q (sair) tambem sai, porque na web so congela a pagina.
# O .pyxapp leva so o que o jogo usa (main.py, arkaway/, assets.pyxres, maps.json), com o marcador de script
# inicial; zip deterministico (Builds/pyxapp.py): dois builds seguidos dao o mesmo sha256.
