/* AdvisorPPC Command Center — mobile-first, app-like design system.
 *
 * Philosophy: phone is the primary canvas (ChatGPT mobile in-app browser + phone
 * browsers). Base styles target a 375px viewport with ZERO horizontal overflow.
 * Desktop (the original left-sidebar layout) is layered on at >= 768px.
 *
 * Chrome model:
 *   mobile  -> .app-bar (top) + .tab-bar (bottom) + off-canvas .nav-drawer (hamburger)
 *   desktop -> sticky left .sidebar + main column (app-bar/tab-bar hidden)
 * The drawer and the sidebar render the SAME _sidebar.html markup.
 *
 * Pure CSS + the tiny inline JS toggle in base.html. No CDN, no framework.
