   BSA CONSULTING — BASE STYLESHEET
   Loaded on every page. Contains only what's identical
   everywhere: tokens, reset, nav, the cinematic scene header,
   buttons, the gold CTA banner, footer, and reveal/motion.
   Page-specific styling lives in its own file (home.css,
   services.css, process.css, results.css, about.css, faq.css,
   contact.css) loaded alongside this one.
