/* =============================================================
   AGENTS — dark-portal landing page. Scent-matched destination for the
   agent campaign creative (docs/ads/linkedin-0727).

   The pinned three-beat sequence is NOT defined here: `.agstage` lives in
   components.css because the homepage runs the same block. Only the
   `.agstage-bare` modifier (drop the intro, tighten the top padding) is
   page-local.

   --dark-bg is overridden to the exact background the stage images were
   rendered on (--stage in assets/agents/src/_base.css). They must stay equal
   or every image shows a visible rectangle against the page.
   Load order: marketing-shell.css → components.css → this file.
