/* Direct Jarvis (AGE-322).

   Chrome (header, footer, .btn, .lead) comes from /assets/styles.css, which is
   where the brand tokens live on this branch and which becomes the @import of
   assets/design/tokens.css once the design-system migration lands. Steps of the
   accent ladder that this branch does not carry yet are written as
   var(--accent-*, <the ladder's own value>), so the token takes over the moment
   it exists and nothing here forks a brand value.

   Spacing and type sizes are the published ladder steps written literally, for
   the same reason: --space-* and --fs-* are not on this branch yet.

   The page is one screen: the wordmark, four buttons and a line of terms. The
   site's own .btn is a 0.76rem micro-label, which is right for a nav button and
   wrong for the only thing on this page, so .amount-btn overrides its height
   and type size rather than adding a second button style. Square corners
   throughout, mono only for micro-labels, teal only on things a viewer can act
   on — except the wordmark's gem and its "powered by Jev" line, which are teal
   because the shipped Jarvis branding draws them that way. */
