Licence
This repository is CC0 1.0 Universal (LICENSE), with two directories scoped out of that waiver.
api/napkin-sketch/ is a vendored copy of
napkin-sketch and
ai-helper/graphic-designer/ is a port from it, and both stay under
its MIT licence.
NOTICE carries the copyright line, the permission text in full, and the four bundled notices the vendored parts reach - the three the Markdown entry brings with it, and the hyphenation patterns the chunks have always carried.
Part of the cheatsheets documentation. The repository is on GitHub, and the example page it documents is here.
