# Compila o Signalworks (quebra-cabeca de assembly, de Charlie Krug, MIT; TypeScript + Vite) a partir do commit
# 63554ea de github.com/ctkrug/signalworks: "npm ci" com o package-lock.json do autor (Node 24.21.0 de
# artifacts/tools) e "vite build" (base relativa, saida em dist/). Mudancas nossas (signalworks/signalworks-fredygames.patch):
#  - index.html: sem as fontes do Google Fonts (preconnect + stylesheet), sem o rodape com links para o GitHub e o
#    portfolio do autor, sem o twitter:card e sem a citacao de jogos de terceiros (TIS-100, EXAPUNKS, Zachtronics)
#    no texto de descricao e na secao "about";
#  - src/styles.css: @font-face das fontes OFL (JetBrains Mono e Space Grotesk, arquivos originais do google/fonts no
#    commit 2fe1e8c), copiadas para src/fonts/ e empacotadas pelo Vite.
#
#   src/FredGames.Bundler/Builds/build-signalworks.sh
#
# Saida: artifacts/build/signalworks-63554ea/{signalworks-63554ea-dist.tar.gz,licenses.txt}; o tar.gz tem que sair
# igual em dois builds.
