# Compila o PepperTown (jogo ocioso com tema de RPG, de Cong Xu, MIT; Phaser 3.55.2 + webpack 5) a partir do commit d02b6e1 de
# github.com/cxong/PepperTown, com o yarn.lock do autor (yarn 1.22.22 --frozen-lockfile, Node 24.21.0). O webpack.production.config.js
# do autor usa a API antiga do clean-webpack-plugin/copy-webpack-plugin e nao roda com as versoes do yarn.lock: o patch traz um
# webpack.fredygames.config.js equivalente.
#
# Mudancas (peppertown/peppertown-fredygames.patch), todas por licenca/origem:
#  - sem a musica (assets/music/overworld.*, "Adorable Ache" de Dragor, CC BY-NC-SA 3.0, nao comercial) nem o codigo que a carrega e toca;
#  - sem os quatro retratos das lojas (portrait-*.png) e sem a imagem do titulo (title.png, com falas de quadrinho): o README credita
#    "Dialog by StarNavigator" sem licenca e sem link verificavel, e esses sao os unicos arquivos que poderiam ser isso; o titulo passa a
#    ser texto com a fonte bitmap do jogo;
#  - sem as animacoes de impacto break01.png e splash04.png, que o README nao credita;
#  - CSP no index.html que bloqueia qualquer requisicao fora da pasta.
# Ficam as artes e sons creditados no README (CC BY 4.0, CC BY 3.0, CC BY-SA 3.0, OGA-BY 3.0, CC0): creditos no LICENSE.txt do jogo.

#   src/FredGames.Bundler/Builds/build-peppertown.sh
#
# Saida: artifacts/build/peppertown-d02b6e1/{peppertown-d02b6e1-dist.tar.gz,licenses.txt}; o tar.gz tem que sair igual em dois builds.
