/**
 * M-Board Unified Layout Stylesheet
 * File: templates/css/layout.css
 *
 * Consolidates all CSS from:
 *   - header_new.php   (navbar / header styles)
 *   - navbar.php       (standalone navbar styles — same tokens as header_new)
 *   - sidebar.php      (sidebar panel styles)
 *   - footer.php       (footer styles)
 *
 * Load via <link> in:
 *   - templates/header_new.php
 *   - templates/blank-header_new.php
 *
 * Dynamic rule (.nh fixed positioning) is a single inline <style>
 * in header_new.php / navbar.php and is NOT included here.
