Colophon & licences

Type

Navigation and site information use IBM Plex Sans. Display type uses Redaction by MCKL. Both are self-hosted and available under the SIL Open Font License 1.1: IBM Plex Sans licence and Redaction licence.

Technology

The site is built with HTML, CSS and JavaScript, served by Node.js over HTTP/2. It uses streamed HTML partials and progressive enhancement; pages still work as complete documents without client-side navigation.

Service worker

No service worker is currently registered. A service worker policy will be added here before offline storage, background updates or related browser behaviour is introduced.
