/* ============================================================
 * Mobile homepage — editorial single-column layout.
 * Ported from the "NgsAdvisory Mobile (Editorial)" draft.
 *
 * The whole block is scoped under .ngs-m and every component class is
 * m- prefixed, so it cannot collide with the desktop homepage classes
 * (.hero, .eyebrow, .faq, .btn ...) that share the document. Shown only
 * at <=880px; above that the desktop sections (.ngs-home-desktop) show.
 *
 * Shared .m-btn primitive lives in mobile-chrome.css (always loaded).
 * Front-page only.
