# Monta o Tiles Collector (puzzle de pares de cores de Dimitri Masson, Ludum Dare 58, MIT; p5.js 2.0.5, LGPL-2.1;
# Bootstrap 5.3.8, MIT) a partir do commit 7987615 de github.com/dhmmasson/tilesCollector. O autor publica o jogo
# como um site Quarto (index.qmd + libraries/ + src/ + assets/); aqui entra so o jogo, numa pagina nossa
# (tiles-collector/index.html) com os mesmos scripts do index.qmd, na mesma ordem.
#
# Mudancas no jogo (tiles-collector/tiles-collector-fredygames.patch): o placar dos desafios diarios (dreamlo.com, com
# as chaves privadas no codigo) vira um placar local no localStorage, com os mesmos nomes de funcao e campos; sem o
# carregamento da fonte do Google Fonts (o sketch nao a usava: nenhum textFont); o menu perde a secao "Settings"
# (chamava Game.setPalette/setColorblindMode/showLeaderboard e colorPalettes, que nao existem neste commit) e
# "Tutoriel" vira "Tutorial". O Bootstrap vem do pacote bootstrap@5.3.8 do npm (o jogo so usa botoes, modal e grade);
# o p5.sound do repositorio nao e usado (o jogo e mudo) e fica de fora. O p5.min.js e o do repositorio, igual byte a byte
# ao lib/p5.min.js de p5@2.0.5.
#
# O p5.js e LGPL: o fonte da versao servida (tag v2.0.5 de processing/p5.js) vai junto, como "sources" do bundle.
#
#   src/FredGames.Bundler/Builds/build-tiles-collector.sh
#
# Saida: artifacts/build/tiles-collector-7987615/{tiles-collector-7987615-dist.tar.gz,licenses.txt}; o tar.gz (pasta dist/)
# sai igual em dois builds seguidos.
