# Compila o Sillage (jogo de esqui 3D low-poly de Alexandre Roudaut / Alex12062012; MIT) a partir do commit 68f7fd0 de
# github.com/Alex12062012/sillage (2026-11-01): Vite 8 + three 0.186.1 (versoes do package-lock.json do autor, npm ci --ignore-scripts) e o
# Node 24.21.0 de artifacts/tools. Mundo, esquiador, sons e musica sao gerados em codigo: nao ha arquivo de arte nem de audio.
#
# Mudancas (sillage/sillage-fredygames.patch): so as pistas geradas pelo jogo. O "Free ride" (relevo AWS/Mapzen e dados do OpenStreetMap das
# estacoes Les Rousses e Avoriaz, ODbL/Licence Ouverte) sai do menu e da lista de estacoes, e o modo online (socket.io para um servidor de
# terceiros) fica desligado, sem baixar o socket.io-client; o index.html ganha caminhos relativos e uma CSP que bloqueia qualquer conexao
# fora do site. Os arquivos de dados das estacoes continuam no fonte publicado mas nao entram no JavaScript servido.
#
#   src/FredGames.Bundler/Builds/build-sillage.sh
#
# Saida: artifacts/build/sillage-68f7fd0/sillage-68f7fd0-dist.tar.gz (dist/); tem que sair igual em dois builds.
