/*
 * The page speaks the app's design system, ported from src/ui/theme.ts in the
 * app repo. The rules that came along with the tokens:
 *
 *   - Colour is semantic, never decorative. Moss is money, amber is the
 *     clock, clay is loss. Nothing gets a colour to look lively.
 *   - Cards are flat: a hairline on paper, no shadow anywhere in this file.
 *   - Every figure that could sit above another figure is tabular. Money is
 *     bold tabular sans, never monospace, which gives the thousands comma a
 *     full character cell. Only the countdown is monospace, because it is
 *     the one string whose letters change every second.
 *   - No webfonts. The page renders in the face the phone already has, which
 *     is also why it makes zero third-party requests.
