/* ============================================================================
   secsip-chrome.css — shared secsip_ header: wordmark + centred pill nav +
   inline hi_ pill + theme toggle. When the bar is squeezed the nav collapses
   into a "⋯" dropdown. Pairs with secsip-chrome.js (which injects the markup).

   All rules are scoped under .secsip so this file is inert on coffee pages even
   if it were ever loaded there. Colours come entirely from secsip-tokens.css.
