Licenses

Parts of this site were built from someone else's MIT-licensed work. One of those parts is compiled into the JavaScript your browser has already downloaded, so the notice for it is published here. The site being closed source does not change that requirement, because the licence follows the code rather than the repository.

lib/morph/compile/align.ts: The closed-form 2D Procrustes solution, the minimal-rotation tie-break, and the global-hybrid pass with block transport.
lib/morph/compile/parse.ts: The path-data grammar and the arc-to-cubic conversion, which follows the SVG specification's centre parametrisation in appendix F.6.
lib/morph/runtime/motion.ts: The shared frame loop, which is the piece that reaches the browser.

The damped-oscillator integration, its settle test and the spring preset constants were derived from the same work. They were removed when the driver moved from a spring to a tween, so none of that code is still here. It is listed because the notice records what this was built from, not only what remains.

The colophon lists the work this book came out of, which is a separate question from licensing.
