# Monta o Infinite Cars (jogo de desviar de obstaculos na estrada, de Takane Ichinose, GPL-3.0; Phaser 3.55.2) a partir do commit 8b05f1d de
# github.com/takaneichinose/infinite-cars: os arquivos estaticos do autor, sem build, com o patch infinite-cars/infinite-cars-fredygames.patch.
#
# Mudanca: so o index.html (CSP que bloqueia qualquer requisicao fora da pasta; sem o console.clear() inline, que a CSP barra). O phaser.min.js do repositorio
# e byte a byte o dist/phaser.min.js do pacote npm phaser 3.55.2 (MIT). Ficam de fora os icones de Android (so servem a um app) e o README/LICENSE (o texto vai em
# LICENSE.txt do jogo e em licenses.txt).
#
#   src/FredGames.Bundler/Builds/build-infinite-cars.sh
#
# Saida: artifacts/build/infinite-cars-8b05f1d/{infinite-cars-8b05f1d-dist.tar.gz,licenses.txt}; o tar.gz tem que sair igual em dois builds.
