/*
 * Shared by all four pages.
 *
 * Colours are the app's own tokens (apps/mobile/src/theme/tokens.ts), so the
 * site and the app cannot drift apart: accent is water and only water
 * (DESIGN-BRIEF §3.1), and both schemes are defined rather than one being
 * derived from the other.
 *
 * No web fonts. Schibsted Grotesk is what the app uses, but loading it from a
 * font CDN would send every visitor's IP to a third party from the page that
 * tells them we do not do that. A system stack is the honest choice here.
