# Exporta o Build and Delve (Paul Gestwicki, 7DRL 2021; GPL-3.0-or-later, github.com/doctor-g/7DRL-2021) para a web
# com o Godot 3.5.3 oficial (o projeto e do Godot 3.x e abre sem mudancas): modelo webassembly_release (sem threads:
# nao precisa de SharedArrayBuffer nem de COOP/COEP), sem PWA. O repositorio traz um export_presets.cfg que nao serve
# para a nossa pagina; o nosso fica ao lado deste script. O projeto (pasta project/ do repositorio) nao muda.

#
# O editor (macOS) e os modelos de exportacao vem do release 3.5.3-stable do GitHub, conferidos pelo SHA-256 e ficam
# em artifacts/tools/godot-3.5.3, instalados sob lockf. O editor roda com HOME dentro da pasta de saida.
#
# Saida: artifacts/build/build-and-delve-a5aa64c/web/, que o bundle.yaml do jogo confere pelo SHA-256.
