/* ============================================================
 * mv-submenu.css
 * Metavoz Design System v2 — Unified Submenu Component
 *
 * Provides 3 variants:
 *   .mv-submenu--tabs   horizontal tab bar (default, replaces mv-tab-bar-v2 for nav links)
 *   .mv-submenu--rail   vertical sidebar (220-260px, for SMS/Mailing sidebars)
 *   .mv-submenu--pills  breadcrumb wizard pills
 *
 * WCAG 2.1 AA: min-height 44px on touch, 4.5:1 contrast on text-muted,
 * focus-visible ring, aria-current="page" on active items.
 *
 * Backward compatibility: .mv-tab-bar-v2 alias block at bottom of file —
 * legacy class names still render identically via CSS mirroring.
 *
 * Load order: AFTER metavoz-theme-v2.css (requires its :root tokens).
 * Introduced: 2026-04-19  (Ola 2 — mv-submenu unification)
