# Compila o Ricochlime (adil192, AGPL-3.0; github.com/adil192/ricochlime, Flutter + Flame) para a web com o
# Flutter 3.47.1 oficial (flutter-web/env.sh instala em artifacts/tools/flutter), em dart2js + CanvasKit
# completo auto-hospedado (sem CDN do Google, sem Google Fonts em tempo de execucao, sem service worker).
#
#   src/FredGames.Bundler/Builds/build-ricochlime.sh
#
# Mudancas no jogo (ricochlime/ricochlime-fredygames.patch, sao as do patches/foss.sh do autor):
#  - sai o in_app_purchase (compras de moedas) e entra a classe vazia _iap_foss.dart do proprio autor;
#  - pubspec.lock sem os pacotes do in_app_purchase (a build usa pub get --enforce-lockfile);
#  - volumes de musica e efeitos comecam em 50% (o original comeca mudo e o jogador nao saberia onde ligar).
# A pasta web/ do projeto (PWA, manifest, icones, pagina de privacidade do autor) e trocada pelas pecas de
# flutter-web/ (index.html com CSP, bootstrap sem service worker, isolamento do localStorage).
#
# Saida: artifacts/build/ricochlime-<commit>/{ricochlime-web.tar.gz, ricochlime-<commit>.tar.gz (o fonte
# exato do autor), ricochlime-web.sha256}, conferidos pelo bundle.yaml do jogo.
