/* ==========================================================================
   Sky-Eagle Designs — blog stylesheet
   ==========================================================================

   Scope: /blog and /blog/<slug> only. The homepage keeps its own inline
   <style> block untouched, so the design tokens and page chrome below are a
   deliberate second copy rather than a shared import. That was the safe
   trade: index.html is live and indexed, and refactoring its CSS as a side
   effect of adding a blog risked a visual regression on the money page.
   If the two ever drift, this file is the one to reconcile.

   Cached hard by nginx (`expires 30d; Cache-Control: immutable` on *.css),
   so bump the ?v= query in the <link> tags whenever this file changes or
   browsers will hold the old copy for a month.
