/*
 * Multicharts Universe — Header (v0.2.1)
 *
 * Sticky cosmic header. Transparent at rest (so hero shows through), gains
 * frosted-glass background once the page is scrolled. Three-section layout:
 * branding · navigation · actions (cart + account + mobile burger).
 *
 * Specificity strategy: prefix every selector with `body.mcu-theme` so we
 * always win against Storefront's customizer-injected inline CSS (which
 * uses bare `.site-header` and friends).
