/* Path: assets/nav.css
 * Version: 1.0.11
 * Last Modified: 2026-10-13
 * Changelog:
 * - 1.0.11 (2026-10-13): One :root custom property --wqd-nav-control-size (44px) for the nav control floor, shared with system-status.php (gate nits, card 3.59.34).
 * - 1.0.10 (2026-10-12, Card 3.59.32 v1.1, backlog #70): .menu-item focus-visible ring (drawn inside, .menu-items clips overflow) and a distinct teal current-page item incl. hover.
 * - 1.0.9 (2026-10-11, release 3.59.31, backlog #47): .menu-item transition narrowed from "all" to opacity, transform, box-shadow, background.
 * - 1.0.8 (2026-09-30, Card 3.59.22 amendment v2e): Scope last-update wrapping, preserve manual subtitle segments, and wrap narrow-screen header actions.
 * - 1.0.7 (2026-09-30, Card 3.59.22 amendment v2c): Apply explicit page-header layout hooks.
 * - 1.0.6 (2026-09-30, Card 3.59.22 amendment v2b): Allow header titles and action groups to share or wrap rows without overflow.
 * - 1.0.5 (2026-09-30, Card 3.59.22 amendment v2): Hide bar labels below 1024px and protect header text from nav compression.
 * - 1.0.4 (2026-09-30, Card 3.59.22): Place the bar cleanly in page headers with dark and light tones.
 * - 1.0.3 (2026-09-30): Delay hidden menu visibility until collapse and reveal for keyboard-visible focus.
 * - 1.0.2 (2026-09-30): Fix PIN input contrast, keyboard menu reveal, and mobile/current-item navigation styles.
 * - 1.0.1 (2026-09-30): Make linked stylesheet valid CSS and reset legacy nav positioning for the bar.
 * - 1.0.0 (2026-09-30, Card 3.59.20): Move kiosk rules and add shared navigation bar styles.
