/* pages/dashboard.css
 *
 * Authenticated app shell. Two-column desktop layout (sidebar + main),
 * sticky in-content header with breadcrumbs on the left and the account
 * dropdown on the right. Below 768px the sidebar slides in as an off-canvas
 * drawer triggered from the header's hamburger.
 *
 * Composes NanoUI primitives (nano-sidebar, nano-dropdown, nano-avatar,
 * nano-breadcrumb, nano-card) - this file owns layout, responsive
 * behavior, and a couple of small modifiers (right-anchored dropdown,
 * sign-out button reset) scoped to the dashboard chrome.
