   globals.css, at /SITE/app/globals.css on the server) — same dark gradient
   scrim and Inter type, but all content horizontally centered rather than
   that site's bottom-left layout. Gradient is centered to match (a
   left-fading scrim under centered copy would look like a leftover).

   Centred on both axes, not bottom-anchored: #tourNav sits at
   `bottom: max(16px, safe-area) + 50px` and runs ~100px tall, which the old
   `align-items: flex-end` + 100-150px bottom padding put the Enter button
   straight through. Centring also matches the radial gradient's own focus.
   `margin: auto` on the inner rather than `justify-content: center` alone, so
   copy taller than the viewport scrolls instead of being clipped at both ends.
   --font-sans/--gutter are the :root tokens (see top of file). */
