/* ==========================================================================
   Drift — landing page (standalone, layout: false)
   ==========================================================================
   A geological "strata" system: warm paper backgrounds, sandstone borders,
   basalt text, a single hot copper accent. Light aesthetic; the page stacks
   full-bleed sections from pale paper down to near-black.

   Tokens are scoped to this page only — this stylesheet is the sole CSS
   loaded by /drift, so it does not touch the main site's variables.css.

   require_self first so the timeline's rules land after this file's — it sets
   `.drift img { height: auto }`, which otherwise wins the specificity tie
   against `.dt__band img` and stops the strip thumbnails filling their bands.
