# Exporta o Pew Pew Pew: Danger Zone! (Gina Haeussge "foosel", Go Godot Jam 4; codigo, arte e sons MIT, musica de
# DavidKBD com os termos dele em assets/music/LICENSE.txt, fonte JetBrains Mono OFL, github.com/foosel/
# pew-pew-pew-danger-zone) para a web com o Godot 4.4.1 oficial (o projeto e do 4.0; o 4.4 abre sem mudancas):
# renderer Compatibility (o unico da web), SEM threads (modelo web_nothreads_release), sem PWA. O projeto do
# autor muda so na fonte: a DIGITAL-7 (freeware "para uso domestico") sai e entra a Orbitron (SIL OFL 1.1,
# google/fonts no commit pinado, conferida pelo SHA-256) no HUD e na tela de creditos. O export_presets.cfg e
# nosso, ao lado deste script.
#
# ATENCAO: este export NAO e bit a bit reprodutivel. O Godot 4 sorteia um unique_id novo para os nos de cada
# cena que converte para binario (export-*.scn em .godot/exported/), entao index.pck muda a cada execucao; o
# resto (wasm, js, icones, o tar.gz do fonte) e identico. O bundle.yaml pina a saida gerada por ultimo; rodar o
# script de novo exige atualizar o sha256 do index.pck (e do index.html, que traz o tamanho dele).
#
#   src/FredGames.Bundler/Builds/build-pew-pew-pew-danger-zone.sh
#
# O editor (macOS) e os modelos de exportacao vem do release 4.4.1-stable do GitHub, conferidos pelo SHA-256
# e ficam em artifacts/tools/godot-4.4.1, instalados sob lockf (outros scripts podem estar instalando ao
# mesmo tempo). O editor roda com HOME dentro da pasta de saida (configuracao e modelo isolados).
#
# Saida: artifacts/build/pew-pew-pew-danger-zone-930ab15/{web/,pew-pew-pew-danger-zone-930ab15.tar.gz}, que o bundle.yaml do
# jogo confere pelo SHA-256. O tar.gz e o fonte publicado (o projeto no commit pinado ja com as mudancas
# acima) e sai igual a cada execucao.
