// Rebuilds referee/sgs.mjs and viewer/ from this folder's src/ and the upstream source.
//   git clone https://github.com/wmzy/sanguosha && cd sanguosha && git checkout 8f4b693 && pnpm install --frozen-lockfile
//   node <this folder>/src/build.mjs <that checkout>            (built with Node 22.19.0, pnpm 10.28.2)
// src/ is copied into <checkout>/shoal/ so it imports the upstream as ../src/..., and the upstream's own Vite builds
// it: the engine as one ES module for Node 20+ (and referee/generals.json from it), the viewer as static files with
// relative paths. `--engine` skips the viewer. viewer/art/ (the art pack) is built apart, by src/art.py, and kept.
