# Compila "I Have Put The Creature Into My Gun" (plataforma de Jez Swanson/Jezzamonn, Ludum Dare 56; MIT; sons
# gerados com jsfxr, Unlicense) a partir do commit 4330453 de github.com/Jezzamonn/LD56, como o package.json do
# autor: "npm ci" (package-lock.json dele), webpack e sass, com o Node 24.21.0 de artifacts/tools. Em producao
# (sem source map) e sem os scripts de instalacao dos pacotes (o "canvas" nativo so serve a ferramentas de
# desenvolvimento do autor).
#
# Mudancas no jogo (i-have-put-the-creature-into-my-gun/creature-fredygames.patch): sem o Google Analytics, sem o
# link para o site do autor (a pagina roda num iframe), uma CSP que barra qualquer requisicao fora do site, os
# modos de depuracao que o jogo liga em "localhost" desligados, e as fontes ChevyRay (o repositorio as ignora:
# *.ttf no .gitignore, nao sao distribuidas com o codigo) trocadas pela Press Start 2P (OFL-1.1, google/fonts num
# commit fixo).
#
#   src/FredGames.Bundler/Builds/build-i-have-put-the-creature-into-my-gun.sh
#
# Saida: artifacts/build/i-have-put-the-creature-into-my-gun-4330453/{dist/,*-dist.tar.gz,licenses.txt}; o tar.gz
# (pasta dist/) tem que sair igual em dois builds seguidos.
