# Compila The Great Train Robbery (Ondrej Zara, 7DRL 2026, MIT) a partir do commit e10b356 de
# github.com/ondras/great-train-robbery, com o Deno 2.9.7 (binario do release oficial, sha256 conferido, em artifacts/tools/).
# O index.js do autor e gerado por "deno bundle --minify src/index.ts"; sem mudancas, o nosso sai byte a byte igual
# ao dele (as dependencias face e rl-display vem do jsDelivr nos commits do deno.lock do autor, que o Deno confere).
# Mudancas em great-train-robbery/no-external.patch: sai a arte ASCII do trem da tela de abertura (o CREDITS.md
# credita a "intro image" a um usuario do YouTube), o link/atalho [7] para o GitHub (window.open) e o link do GitHub
# da ajuda. A fonte Cascadia Mono (woff2, SIL OFL 1.1) ja vem no repositorio.
#
#   src/FredGames.Bundler/Builds/build-great-train-robbery.sh
#
# Saida: artifacts/build/great-train-robbery-e10b356/great-train-robbery-e10b356-dist.tar.gz (pasta dist/; igual em dois builds).
