# Compila o Fire & Fondness 2 do fredygames.com: o jogo de John Gabriel (codigo GPL-3.0, arte e musica
# CC BY 4.0), a partir do tarball do commit 1e8e10f do repositorio JohnGabrielUK/fire-and-fondness-2
# no Bitbucket, exportado para HTML5 com o Godot 3.2.2 oficial (a versao em que o autor fez o jogo) e o
# modelo web dele, pelo preset "HTML5" do export_presets.cfg do proprio projeto. Este script e o patch
# ao lado dele sao parte do codigo-fonte publicado junto do jogo ("the scripts used to control
# compilation" da GPL).
#
#   src/FredGames.Web/Content/games/fire-and-fondness-2/engine/build.sh
#
# As tres fontes do lancamento original (SGK075, V5 Prophit e Visitor) nao tem termos que permitam
# redistribuir num site com anuncios; o script as apaga da arvore e poe no lugar fontes SIL OFL 1.1,
# arquivos sem modificacao conferidos pelo SHA-256:
#   - Ark Pixel Font 10px proporcional (latin), de TakWolf, release 2026.09.25 (texto corrido, no
#     lugar da SGK075);
#   - Silkscreen Regular e Bold, de Jason Kottke, do repositorio google/fonts (interface e titulos, no
#     lugar da Visitor e da V5 Prophit).
#
# fire-and-fondness-2-fredygames.patch:
#   - game/fonts/*.tres: as tres DynamicFont apontam para as fontes novas, no tamanho em que cada uma
#     fica nitida (um pixel da fonte = um pixel do jogo);
#   - game/export_presets.cfg: no preset "HTML5", um html/head_include que da foco ao canvas quando a
#     pagina carrega e quando o iframe recebe foco (o Godot 3.2 so le o teclado com o canvas em foco;
#     sem isso, as setas rolariam a pagina do site em volta do jogo);
#   - README: os creditos das fontes.
#
# O Godot 3.2.2 (macOS, x86_64, roda no Rosetta) e o modelo HTML5 ficam em artifacts/tools/godot-3.2.2,
# conferidos pelo SHA-256 (os mesmos arquivos do SHA512-SUMS.txt do release). O editor roda com HOME
# dentro da pasta de saida, onde ficam a configuracao dele e o modelo de exportacao.
#
# Saida: artifacts/build/fire-and-fondness-2-1e8e10f/web/, que o bundle.yaml do jogo confere arquivo
# por arquivo.
