/* Homepage phone header and hamburger menu.
   The header stays fixed: transparent over the hero, a solid frosted bar after scrolling (.is-scrolled,
   toggled in mobile-sections.js) or while the menu is open (body.noScroll, toggled by hamburger.ts).
   Selectors carry the same html:not([data-hero-layout="previous"]) prefix as hero-code-concept.css so they win. */
