# Exporta o Librerama (Yeldham/Librerama, versao 0.7.0; codigo GPL-3.0-ou-posterior, assets CC BY-SA 4.0, creditos de
# cada nanogame em nanogames/*/nanogame.json; codeberg.org/Librerama/librerama) para a web com o Godot 4.7.2
# oficial (o projeto pede o 4.6.x; o 4.7 abre o projeto sem mudancas): renderer Compatibility, SEM threads
# (modelo web_nothreads_release: nao precisa de SharedArrayBuffer nem dos cabecalhos COOP/COEP), sem PWA.
# O repositorio traz um preset Web que liga o isolamento COOP/COEP; o nosso (librerama/export_presets.cfg) o
# desliga e deixa de fora o que o jogo nao usa (distribution/, fastlane/, tools/, addons/).
# Mudancas no projeto, todas feitas aqui e visiveis no fonte publicado:
#  - OS.shell_open(meta) (os cinco pontos em que um link dos textos abriria outro site: lobby, "sobre", "sobre o
#    nanogame", colecao e fliperama) passa a nao fazer nada: os links ficam sem acao, o jogo nao leva ninguem
#    para fora do site. Os creditos continuam todos na tela (cada nanogame mostra autor, licenca e fonte do
#    que usa, e o "sobre" lista Godot, FreeType, Noto e os sons do lobby);
#  - o jogo ja tolera a ausencia de threads (Thread.start falha e o codigo instancia o nanogame na hora), por isso
#    o nanogame_player.gd fica como esta.

#   src/FredGames.Bundler/Builds/build-librerama.sh

# Saida: artifacts/build/librerama-740d349/{web/,librerama-740d349.tar.gz}, que o bundle.yaml do jogo confere
# pelo SHA-256. O tar.gz e o repositorio do commit com as mudancas acima (GPL: o fonte exato do que e servido)
# e sai igual a cada execucao.
