# Compila o Yet Another Idle RPG (RPG ocioso de texto e CSS, de Miktaew, MIT; JavaScript puro em modulos ES) a partir do commit e335643
# (v0.5.5.30) de github.com/miktaew/yet-another-idle-rpg. O projeto nao tem package.json: o autor roda o esbuild na mao (build.js).
# Aqui o esbuild 0.28.1 vem de yet-another-idle-rpg/package-lock.json ("npm ci", com hashes de integridade) e roda com as mesmas
# opcoes do build.js (bundle, minify, es2022, esm), sem source map; o dist/bundle.js do repositorio nao entra.
#
# Mudancas (yet-another-idle-rpg/yet-another-idle-rpg-fredygames.patch): CSP em cada pagina (nada fora da pasta); o Material Icons
# do Google Fonts vira o pacote npm "material-icons" 1.13.14 (Apache-2.0, woff2/woff conferidos pelo sha256 do tarball); a Ink Free
# (fonte proprietaria da Microsoft) vira a Patrick Hand (OFL, do google/fonts em commit fixo); sem meta tags og:/JSON-LD/verificacao
# do Google, sem os botoes do GitHub e do Ko-fi nem as imagens deles (github-mark-white.png, ko-fi_icon.png), favicon local, e a
# ajuda (help.html) sem links para fora e sem a secao de doacao. O HackTimer (MIT) do repositorio segue como esta.
#
#   src/FredGames.Bundler/Builds/build-yet-another-idle-rpg.sh
#
# Saida: artifacts/build/yet-another-idle-rpg-e335643/{yet-another-idle-rpg-e335643-dist.tar.gz,licenses.txt}; o tar.gz tem que
# sair igual em dois builds.
