# Compila o Cellular: Automata (puzzle de cartas de autômatos celulares de Ilya Baturinsky, Ludum Dare 46; MIT; Preact,
# MIT; fonte Didact Gothic, OFL-1.1) a partir do commit 4ae7c2f de github.com/baturinsky/cellular, como o package.json
# do autor: yarn 1.22.22 (yarn.lock dele, "--frozen-lockfile", sem os scripts de instalacao) e "rollup -c" (TypeScript,
# terser), com o Node 24.21.0 de artifacts/tools. O public/bundle.js que o autor commitou e substituido pelo gerado.
#
# Mudancas (cellular-automata/cellular-fredygames.patch): o main.css deixa de apontar para a copia da fonte no
# fonts.gstatic.com (a mesma fonte ja vai junto, DidactGothic.woff) e o index.html ganha uma CSP que barra qualquer
# requisicao fora do site. O codigo do jogo nao muda. Vai junto a OFL da fonte, do google/fonts num commit fixo.
#
#   src/FredGames.Bundler/Builds/build-cellular-automata.sh
#
# Saida: artifacts/build/cellular-automata-4ae7c2f/{cellular-automata-4ae7c2f-dist.tar.gz,licenses.txt}; o tar.gz
# (pasta dist/) sai igual em dois builds seguidos.
