 * IMPACCT 2.0 — Base Layout
 * Sidebar (collapsible + resizable), topbar, content area, responsive.
 * All colors use theme CSS variables from theme.css.
 *
 * Sidebar behavior:
 * - User can collapse/expand via toggle button (hamburger ☰ / ✕)
 * - User can drag the right edge to resize between 180px–400px
 * - Collapsed state shows only icons (56px wide)
 * - Width and collapsed state persist in localStorage
 * - Main content margin adjusts dynamically via --sidebar-width
