   Cruxsmith — base stylesheet (functionality MVP)
   Placeholder "granite + ember" palette. All color/spacing lives in CSS
   variables so the design pass can reskin from one place.
   effects.css already provides: skip link, preloader, text-reveal, noise,
   focus ring, .nav-cta, .hamburger, smart-nav transform, mobile glass nav,
   back-to-top, reduced-motion. This file styles everything else.
