/* The pages that live outside the chat: sign in, register, account, usage and
 * credits, plans, users, feedback, policies.
 *
 * chat/app.css is linked first and owns the whole visual system — colour,
 * radius, shadow, type, motion. Nothing here redefines a token; this file only
 * adds the page-level layout and the handful of controls (buttons, fields,
 * tables, cards) the chat itself has no use for. Where a value has to be
 * literal it is expressed as a mix of two tokens, so it follows the theme into
 * dark mode instead of staying stubbornly light.
 *
 * The chrome is a deliberate copy of the chat's rail rather than a variation on
 * it: same width, same hairline, same account block pinned to the bottom. People
 * cross between the two surfaces constantly and should not notice the seam.
