/* ============================================================================
   /zetai — implementation of the "Zet AI Page" Claude Design mockup
   (project 2e3af89d-2585-434f-9b42-d95402af3ddc).

   Tokens below are imported verbatim from the Zeetius design system attached to
   that project (_ds/zeetius-design-system-.../tokens/*.css), with ONE deliberate
   change: the design system declares them on :root and restyles body/h1-h4/a
   globally. Loading that as-is would restyle the whole site — the shared header,
   footer and every other page render inside the same document. So every token
   and every element rule is scoped to .zt-page instead.

   Keep the values identical to the design system. Change them there first.
