## Renderer

Based on Adriwin06/black-hole, commit b62f3cbd680b905e9fe4c36d6bdc0db423c6bb7c:
https://github.com/Adriwin06/black-hole/tree/b62f3cbd680b905e9fe4c36d6bdc0db423c6bb7c

First-party code is MIT, copyright 2015 Otto Seiskari and 2026 Adriwin.
Full text: LICENSE-Adriwin.txt. The original header and source comments are retained.

Retained: shader.js, observer.js, presets.js, quality-presets.js, bloom.js, and the ordered GLSL shards combined into gargantua.glsl.
Extracted from renderer.js: temporal AA and Halton helpers (temporal-aa.js), and adapted uniform/ISCO wiring (uniforms.js).
New ZeroVessel adapter: fixed hero camera, lifecycle/pause controls, procedural textures, A-layout brand shell.

The Gargantua (Interstellar visuals) preset is retained. Planet and observer orbit are disabled. Desktop uses Optimal quality, mobile uses Mobile quality. Mobile camera distance and the off-axis framing are adjusted for the existing A layout.

## Libraries actually shipped

- three.js r73, MIT, copyright 2010–2015 three.js authors. See LICENSE-Three-r73.txt.
- Mustache.js 2.2.0, MIT, Chris Wanstrath, Jan Lehnardt, and the mustache.js community. See LICENSE-Mustache-2.2.0.txt.

No dat.GUI, jQuery, Font Awesome, recording libraries, remote fonts, CDN resources, or upstream photos are shipped in this preview.

## Images and generated data

No assets/img/milkyway.jpg or other upstream image asset is copied into the preview. In particular, the CC-BY-NC Milky Way image is not used.
The star atlas, empty photographic sky/planet samplers and visual RGB spectral lookup are generated locally by ZeroVessel's textures.js. The spectral lookup is a visual approximation, not the upstream calibration or a scientific accuracy claim.
The portrait is the user's existing local avatar, embedded unchanged in the About dialog.
