# Compila o Split Push (puzzle de Florian Castel, Gamedev.js Jam 2025; codigo MIT, arte e efeitos CC BY 4.0,
# musica de Eric Matyas sob a Soundimage International Public License; Phaser 3 + TypeScript) a partir do
# fonte, num commit fixo, como o README do autor: "npm ci" (package-lock.json do autor, com os hashes de
# integridade do npm) e "webpack --mode production", com o Node 24.21.0 de artifacts/tools.
#
# Mudancas no jogo (split-push/split-push-fredygames.patch): sem o Google Fonts (Poppins e Roboto Mono sao
# servidas de assets/fonts, SIL OFL 1.1, do google/fonts num commit fixo), sem o <script src="/bundle.js">
# duplicado e absoluto do index.html, sem quatro load.image de arquivos que nao existem no repositorio, uma
# politica de seguranca (CSP) que bloqueia conexoes fora da propria origem e os creditos da arte (CC BY 4.0)
# e da musica (licenca da Soundimage) com link, na pagina do jogo.
#
#   src/FredGames.Bundler/Builds/build-split-push.sh
#
# Saida: artifacts/build/split-push-32bc743/{dist/,split-push-32bc743-dist.tar.gz,licenses.txt}; o .tar.gz
# (pasta dist/) tem que sair igual em dois builds seguidos.
