/*
 * public/design/client/_shared/sidebar.css
 *
 * Styles for the shared client sidebar component (sibling: sidebar.js).
 * Owner / Manager facing — brand blue gradient (#1e40af → #3b82f6) instead
 * of the admin purple (#7c3aed → #c026d3) so the audience is obvious at a
 * glance.
 *
 * Layout strategy — mirrors the admin sidebar:
 *   • Desktop (>= 1024px): sticky `position: sticky` left column 240 px wide,
 *     inside the `.lz-client-layout` flex container. Page lives in the right
 *     `.lz-client-main` column, no body padding hack.
 *   • Mobile (< 1024px): off-canvas drawer + backdrop, opened by a hamburger
 *     button. Many client pages still ship a bottom `.mobile-nav` bar so the
 *     hamburger is anchored TOP-LEFT (well clear of the bottom bar).
 *
 * All class names are namespaced `lz-csb-` / `lz-client-` (Client SideBar)
 * so they never collide with the admin sidebar's `lz-sb-` / `lz-admin-`
 * classes — both sidebars can coexist in the DOM during a multi-page audit.
