 * Hartii Biome — shared base.
 *
 * The previous page led with Bodoni Moda, a high-contrast classical serif. It is a beautiful face
 * and it was making a Web3 product hub read like a perfume advert: romantic where the content is
 * technical. Display type is now Space Grotesk — the same face the QuaiAxe site uses, already
 * self-hosted in this repo, so no new request and one consistent voice across the ecosystem.
 *
 * Palette stays black and red (no gold, per house rule) but is built as a proper token set:
 * layered near-blacks that carry a slight red bias so surfaces separate without borders
 * everywhere, and exactly one accent that is spent only on the thing you should click.

   RESTORES the nav below 760px.

   wallet.css hides .nav-links under 760px and reveals a .nav-burger, because the page it was
   written for had a burger and a slide-out drawer. This nav is deliberately minimal and has
   neither, so that rule left phones with NO navigation at all - the links were present in the
   DOM at 0x0, which body{overflow-x:hidden} then hid completely rather than revealing as a
   layout bug. Five short links wrap onto one extra line perfectly well at 375px, so they stay.
