# Monta o Learn Git Branching (visualizacao interativa de git, de Peter Cottle, MIT) a partir do commit c7ed929 de
# github.com/pcottle/learnGitBranching: "yarn install --frozen-lockfile" com o yarn.lock do autor (yarn 1.22.22, do pacote npm, conferido
# pelo sha256, e Node 24.21.0), "node scripts/generate.js", "vite build" e o postbuild do autor (copia assets/). Sem o "yarn test".
# Mudancas nossas (learn-git-branching/learn-git-branching-fredygames.patch): sem Google Analytics, sem as faixas de divulgacao de outros
# projetos do autor (BiteRead e WaitingFor) e a logica que as sorteia, sem a meta de redes sociais e o canto do GitHub, sem o carregador
# de niveis de gist do GitHub, sem os botoes de compartilhar (Twitter/X, LinkedIn, Facebook), sem o icone do Threads, sem os links de
# documentacao do git-scm.com, sem os links "learngitbranching.js.org" (o link permanente do "export tree" usa a propria pagina e os
# links alternativos de idioma saem), os links Markdown dos textos das licoes e dos dialogos para outros sites viram so texto (os que
# apontavam para o jogo no site do autor viram links relativos), uma Content-Security-Policy e uma trava que impede o jogo de sair da
# propria pagina por um link. Do build saem ainda as imagens de divulgacao (biteRead.png, waitingFor.png, learnGitBranching.png), as
# fontes em formatos antigos (eot/svg/ttf, o CSS cai no woff2/woff) e a documentacao gerada (generatedDocs/).
#
#   src/FredGames.Bundler/Builds/build-learn-git-branching.sh
#
# Saida: artifacts/build/learn-git-branching-c7ed929/{learn-git-branching-c7ed929-dist.tar.gz,licenses.txt}; o tar.gz sai igual em dois builds.
