NOTICE — third-party licence for the files in this directory (`demo/`)
=====================================================================

What this directory is
----------------------
`demo/**` is a **redistributed static build of the WebWallGL web test bench**,
patched by this project. It is served as the online demo / test bench of this
repository. It is **not** part of this project's own renderer code.

Upstream
--------
  Project:   WebWallGL
  Repository: https://github.com/oneincase/webwallgl
  Licence:   MIT
  Copyright: Copyright (c) 2026 oneincase <462534624@qq.com>
  Commit used: fdfc578a577d0e680a9cfe2cf2e3e825d3cd2372  (version 1.3.23, 2026-09-15)

What is upstream, and what is ours
----------------------------------
* **Upstream, redistributed unchanged** — the built artifacts and static shell,
  e.g. `assets/renderer-*.js`, `assets/bench-*.js`, `assets/bench-*.css`,
  `index.html`, `renderer/index.html`, `default-wallpaper/index.html`,
  `icons/*`, `manifest.webmanifest`, `sw.js` (banner/branding strings and the
  minified bundles still carry the upstream "WebWallGL" name).
* **Ours (this project), GPL-3.0-or-later** — `bench-patch.js`, a run-time patch
  loaded by `index.html` with `type="module"`. It does **not** modify the
  minified artifacts; it only reads the DOM / the `#resolution` value and
  dispatches `change`, reusing the bundle's existing code paths. Its behaviour
  is documented in `../docs/ONLINE-DEMO.md` and `../PATCHES.md` (P-93).
  A separate, earlier one-file port of upstream's FXAA fragment shader into this
  project's own renderer is documented in `../THIRD-PARTY.md` §6.

Licence flow
------------
MIT → GPL-3.0-or-later is a **permitted one-way flow** (`../docs/COPYING-RULES.md`
§2.1). The upstream MIT notice below **remains in force for the upstream
material redistributed in this directory** and must keep travelling with it.
Nothing flows back: this project's GPL code must never enter
`oneincase/webwallgl`.

No wallpaper content
--------------------
Nothing in this directory contains a wallpaper package, preview image, audio or
video, or any Steam Workshop content. The bench's default scene is this
repository's own programmatically generated synthetic sample
(`../samples/sample-synthetic/`, 33 299 B), and the page's offline notice says
so. Wallpapers must be supplied by the user from their own lawful copies.
