Typefaces
Served from this domain rather than a font CDN, which is better for privacy — your browser never contacts a third party to render this page — and means this site redistributes the font files, so the licence notice belongs here.

What is not here
Every icon, diagram and graphic on this site is drawn in code — SVG paths and generated geometry — and the 3D work is built from primitives rather than loaded models. So there is nothing further to credit: no icon sets, no stock photography or illustration, no textures, HDRIs or 3D models, no audio or video.
The full audit went wider than this page. Every production dependency was resolved and its licence read: seventeen packages, all permissive — MIT, Apache-2.0, BSD-3-Clause, ISC, 0BSD, and CC-BY-4.0 on one build-time data package. No copyleft, nothing unlicensed, and nothing restricting commercial use.
Our own material
Everything else — the design, the copy, the brand and the code written for this site — is ours, and is covered by the terms of use.
