/*
 * The look of the game, on a page that has to be readable for twenty minutes.
 *
 * These pages are PLAIN HTML on purpose. A terms page that needs a JavaScript bundle to render is
 * a terms page a crawler, a screen reader on a bad connection, a regulator and Stripe's own
 * checkout preview may all fail to read, and Stripe requires a URL that resolves to the document
 * itself. So: no framework, no fonts to fetch, one stylesheet, and every colour taken from
 * `game/src/styles/tokens.css` so the pages belong to the same city as the game.
 *
 * The type is deliberately larger and the measure deliberately narrower than the game's UI. The
 * game is a dense instrument panel; this is prose somebody has to actually read.
