# Compila o Hexa Battle (RPG tatico em grade hexagonal contra a IA, de Giacomo Tagliabue, MIT; TypeScript + React 15 + SVG) a partir
# do commit fe97718 de github.com/itajaja/hb, com o yarn.lock do autor ("yarn install --frozen-lockfile", yarn 1.22.22, Node 24.21.0)
# e "webpack -p" (webpack 2.5). A API do webpack 2 ainda roda no Node 24, so o md4 precisa do provedor legado do OpenSSL.
#
# Mudancas (hexa-battle/hexa-battle-fredygames.patch): caminhos relativos (publicPath ./) em vez de /static/, sem source map, e no
# index.html uma CSP que bloqueia qualquer requisicao fora da pasta e as folhas de estilo locais no lugar dos links do cdnjs
# (normalize.css 4.2.0, MIT, do pacote do npm conferido pelo sha256) e do Google Fonts (VT323, OFL, do google/fonts em commit fixo).
# O jogo nao tem audio e so usa localStorage (lib "store"). Os icones SVG sao do game-icons.net (CC BY 3.0): creditos em LICENSE.txt.
#
#   src/FredGames.Bundler/Builds/build-hexa-battle.sh
#
# Saida: artifacts/build/hexa-battle-fe97718/{hexa-battle-fe97718-dist.tar.gz,licenses.txt}; o tar.gz tem que sair igual em dois builds.
