/*
 * Nocturne, as much of it as a legal page needs.
 *
 * The values are lifted from src/theme/nocturne.ts in the app repo, but this
 * file deliberately does not import or generate from it. The app's design
 * system is React Native objects compiled into a bundle; reaching for it here
 * would couple a document that must be publishable in an afternoon to the
 * release cycle of an iOS app. Six colours and a font stack is the entire
 * overlap, and if they ever drift, the reader sees a slightly different shade
 * of purple rather than an unpublishable page.
 *
 * No web font. The app uses Inter, but loading it from a font CDN would send
 * every reader's IP address to a third party — on the page whose job is to
 * list the third parties. The system stack is close enough and costs nothing.
