Modifications to redrock for this site
======================================

Original: https://github.com/StarKnightt/redrock
Commit:   3f89603f8c72dbd6ab69caee04934f71f4574203

Changes:
- index.html: the import map pointed at /node_modules/three/build/three.module.js.
  It now points at ./vendor/three.module.js (the same rewrite the author's own
  tools/pages.mjs deploy script performs).
- vendor/three.module.js: three.js 0.170.0 (the version pinned in the repo's
  package-lock.json), downloaded unchanged from the npm registry
  (https://registry.npmjs.org/three/-/three-0.170.0.tgz), with its MIT LICENSE
  as vendor/LICENSE-three.js.txt.
- Only runtime files were copied: index.html and src/. The tools/ folder,
  PROMPT.md, social.png, package files and the GitHub workflow were left out.
- index.html line endings are LF (the Windows checkout had CRLF).
- LICENSE-NOTE.txt added (the repo states its ISC license in README.md and
  package.json only; README.md is copied unchanged).

No game code in src/ was changed.
