/*
 * The three legal documents notfour.com serves: /privacy, /terms and
 * /impressum. Static pages, no JavaScript, and nothing loaded from anywhere
 * but this site — Instrument Sans is served from /fonts here rather than from
 * Google's servers, because a German site that fetches a font from a third
 * party has told that party who is reading, and these pages of all pages must
 * not.
 *
 * Every number is the app's own: the tokens of docs/notfour-spec.md and the
 * four spacings of `layout.legal` in src/theme/theme.ts (32 between sections, 6
 * under a heading, 10 between paragraphs, 32 to the date), so the page a person
 * opens in a browser is laid out exactly as the same document is in the app.
