/*
 * Welcome page (#207, v2) for a visitor who has not signed in. Colours, spacing and the font are the
 * tokens of the new interface (`/welcome/tokens.css` = public-new/shared/tokens.css); the dark
 * sections have their own palette below, every text pair on it is at least 7:1 (WCAG AAA 1.4.6).
 * The only script is `/welcome/landing.js`: it reveals the cases on scroll. Without it, or with
 * «reduce motion», everything is simply visible.
