/* =============================================================
   BLUE ROOM STUDIO — SHARED STYLESHEET
   /css/styles.css

   Linked from every page. Contains everything that is identical
   across all six pages. Page-specific rules (hero sizing,
   page sections) stay in each page's inline <style> block.

   Sections:
     1. Variables
     2. Reset & base
     3. Navigation
     4. Hero structural components (sizing stays page-specific)
     5. Utility
     6. Footer CTA  (about.html overrides this to a dark variant)
     7. Site footer
     8. Responsive overrides for the above
