/* Landing navbar styles.
 *
 * Extracted from the inline <style> block in pages/index.html so any page
 * that renders the landing navbar (via the session-aware /api/layout/navbar
 * endpoint) can pick them up via <link>. Previously these styles travelled
 * only with pages/index.html, so pages like /login and /register that also
 * load the landing navbar had unstyled buttons and a broken top bar.
 *
 * This file is additive: pages/landing.css still owns the shared landing
 * color variables and base selectors. Load order on any page: fonts →
 * variables → base → landing.css → landing-nav.css. The button styles use
 * !important to override the minified base rules in landing.css. */
