How it is made.
Everything on this page can be checked against the repository.
Type
Fraunces for display, Instrument Sans for text, IBM Plex Mono for figures and labels, Newsreader in the notes. All four under the SIL Open Font License, served from this domain.
Stack
Next.js as a static export. No server, no database, no build-time secret. The pages are files.
Hosting
GitHub Pages, from a public repository. A push is a deploy.
What it does not do
No analytics, no trackers, no third-party request after the page has loaded. The language you choose is remembered in your own browser and nowhere else.
Licences
Third-party notices. The instruments and tools are open source; each repository names its licence.
