# Monta o Pocket Dimensions RL (Lauren Hall, 7DRL 2019, MIT) a partir do commit e780294 de
# github.com/laurheth/pocket-universe-7drl, sem etapa de build do autor. Mudancas em pocket-dimensions-rl/no-external.patch:
# o rot.js 2.0.3 (BSD-3) deixa de vir do jsDelivr e vai junto (mesmo arquivo do npm, sha256 conferido), e a Overpass Mono
# deixa de vir do Google Fonts: a OverpassMono[wght].ttf (SIL OFL 1.1) do google/fonts no commit pinado vai junto, em fonts/.
# O index.html ganha tambem <meta charset="utf-8">: sem ele o navegador le o texto UTF-8 como Latin-1.
