   responsive.css
   Every @media query in the project lives here — and only here — so the
   full set of breakpoint behavior can be audited in one file. Organized
   mobile-first: each tier progressively enhances the mobile baseline
   defined in the component files, ascending by min-width, followed by
   the tablet-only exception range, print, and reduced-motion.

   Tiers (test at 320/360/390/414/768/1024/1280/1440 per the brief):
     ≥30.0625em (481px)  → breathing room opens up slightly
     ≥48.0625em–64em     → 769–1024px tablet nav tightening (bounded)
     ≥56.3125em (901px)  → desktop: horizontal nav, fluid type resumes
