// Lint for the native-ESM codebase (#155 PR 2 of 10).
//
// Every first-party file is now a real ES module with explicit imports, so
// no-undef is ON: any bare identifier that isn't imported or a known browser
// global is an error. THREE stays a classic CDN global (r128), so it is
// declared here instead of imported. no-unused-vars stays off until the
// split PRs land (game.js still exports a wide surface).
