 * Sidebar theme on top of Tabler (lib/tabler). Tabler's core files are not modified;
 * all colors and sizes are --sb-* variables, so the light/dark themes only change
 * their values. The theme is chosen with data-sb-theme="light|dark" on <aside class="sb">.
 *
 * Modes (set by window.sidebarMode() in _Layout.cshtml and js/sidebar.js):
 *   html.sb-rail     sidebar collapsed to a row of icons
 *   html.sb-overlay  tablet: sidebar opened in full, temporarily over the content
 *   html.sb-open     phone: off-canvas drawer open
