# Compila o gaarden (brinquedo-jardim de Jez Swanson/Jezzamonn, Ludum Dare 45; MIT; sons sintetizados no codigo com
# Tone.js, MIT) a partir do commit 2b2ff90 de github.com/Jezzamonn/gaarden, como o package.json do autor: "npm ci"
# (package-lock.json dele), webpack 3 + babel 6 (com o Node 24.21.0 de artifacts/tools e o provedor "legacy" do
# OpenSSL, que o webpack 3 precisa para o hash md4) e a pagina de src/index.html.
#
# Mudancas (gaarden/gaarden-fredygames.patch): o index.html perde o Google Analytics, os favicons e as tags do
# Facebook/Twitter (apontavam para o site do autor) e ganha uma CSP que barra qualquer requisicao fora do site.
# O codigo do jogo nao muda. Bundle em producao (-p) e sem source map.
#
#   src/FredGames.Bundler/Builds/build-gaarden.sh
#
# Saida: artifacts/build/gaarden-2b2ff90/{gaarden-2b2ff90-dist.tar.gz,licenses.txt}; o tar.gz (pasta dist/) sai
# igual em dois builds seguidos.
