/* The ad manager panel (/advertising), 2026-09-21.

   base.html loads this inside {% block styles %}, which sits BEFORE editorial.css,
   banner-ads.css and ad-images.css. Those three also style the manager, so every rule
   here is scoped with #ad-manager: an id beats their class selectors whatever the order.

   Two things this file is responsible for:
     1. one spacing scale for both columns, and labels that are never clipped;
     2. the preview box showing each placement at the shape the live site really draws
        (measured in the browser; the frames are set by .ad-creative in ad-images.css).
