# Monta os mini-jogos do Santa Tracker do Google (google/santa-tracker-web, commit 7b7b0d1: codigo Apache-2.0,
# imagens e audio CC BY 4.0) como jogos independentes. O projeto original so roda dentro do shell dele (Firebase,
# analytics, roteador, fontes e decodificador Draco do Google); aqui o shell e trocado por um host nosso
# (santa-tracker/host/: pagina com barra de pontos/pausa/reiniciar, protocolo MessageChannel igual ao do original,
# som pelo kplay.js do proprio projeto), e a cena de cada jogo vai como o projeto a publica (api.js e kplay.js sem
# mudanca), com as poucas edicoes listadas em santa-tracker/games.json.
#
#   src/FredGames.Bundler/Builds/build-santa-tracker.sh [slug ...]

# Saida: artifacts/build/santa-tracker-7b7b0d1/<slug>/{<slug>-dist.tar.gz} (a pasta dist/ tem que sair igual em
# dois builds seguidos) e licenses.txt (jQuery MIT, Roboto e Lobster OFL).
# Ferramentas (fora do git): Node 24.21.0, dart-sass 1.107.1 e Closure Compiler 20240317 em artifacts/tools.
