# Monta o Pulse (jogo de tiro no escuro com radar, de Jed Whitten, Ludum Dare 59; MIT; Phaser 3.80.1, MIT; fontes Orbitron e
# Share Tech Mono, OFL-1.1) a partir do commit 9d69f0a de github.com/jswhitten/ld59, sem etapa de build do autor.
# Mudancas em pulse/pulse-fredygames.patch: so o index.html. O Phaser 3.80.1 deixa de vir do jsDelivr e vai junto, pelo
# mesmo arquivo do pacote do npm (sha256 do .tgz conferido), e as fontes do Google Fonts vao junto, em fonts/, do
# google/fonts num commit fixo (sha256 conferido), com uma CSP que barra qualquer requisicao fora do site.
#
#   src/FredGames.Bundler/Builds/build-pulse.sh
#
# Saida: artifacts/build/pulse-9d69f0a/{pulse-9d69f0a-dist.tar.gz,licenses.txt}; o tar.gz (pasta dist/) sai igual em dois builds
# seguidos.
