/* ============================================================
   stantscherenkow.com v2 : shared header + footer + tokens

   CRITICAL: This file contains ONLY tokens, reset, containers,
   skip-link, masthead, and footer. Never add hero styles, card
   components, action band, body typography, or page-specific rules.
   Those live inline on each page.

   Any component class defined here must NEVER be redefined in a
   page's inline <style> block. If a page needs a variant, add a
   modifier class here, not an override there.
