# Compila o Coric's Quest (RPG de console em 2D de Tung Nguyen, MIT; Rust + Miniquad para wasm32-unknown-unknown) a partir do commit
# 215476b de github.com/tung/corics-quest, como o "task wasm-site" do autor: cargo build --release --locked --target
# wasm32-unknown-unknown (Cargo.lock do autor, Rust 1.92.0 de artifacts/tools/rustup). Imagens, musicas e fases entram no .wasm por
# include_bytes!. A pagina (corics-quest/index.html + start.js) e nossa, com CSP sem rede externa; os JS do Miniquad (gl.js), do
# quad-snd (audio.js) e do sapp-jsutils vem das caixas do crates.io ja conferidas pelo Cargo.lock, e o quad-storage.js do commit
# a359374 de optozorax/quad-storage (o da versao 0.1.2 do plugin, a mesma do quad-storage-sys 0.1.0).
#
# Mudancas (corics-quest/patch.py): a fonte bitmap hp-100lx-6x8.png, sem credito nem licenca, e trocada por uma gerada de Spleen 5x8
# (BSD-2-Clause) por corics-quest/make-font.py; as chaves do save e das opcoes no localStorage levam o prefixo "corics-quest.".
#
#   src/FredGames.Bundler/Builds/build-corics-quest.sh
#
# Saida: artifacts/build/corics-quest-215476b/{corics-quest-215476b-dist.tar.gz,licenses.txt}; o tar.gz tem que sair igual em dois builds.
