/* =============================================================================
   DIGITAL GARDEN SKIN (body class `dg-garden`)
   -----------------------------------------------------------------------------
   /digital-garden/ listing and every `garden` collection guide. Pure black
   page, white type, Aptos (ships with Windows 11 / Microsoft 365; elsewhere it
   falls back to the system sans), matching the Sessions page's black canvas.
   Cards copy the Signals card anatomy (tag / title / text / foot rule) in a
   two-per-row grid. The nav keeps its Space Mono face, as on other skins.
   Gate is duplicated in _includes/head.html and _layouts/default.html.
