/**
 * HOA Management System — App Shell Overlay
 *
 * Visual-only adaptation of the existing shell (#header / #app-sidebar /
 * .main-content / #notification-panel / #global-search-overlay) inspired by
 * the reference SaaS design language. Brand stays HOA green.
 *
 * Strict rules followed:
 *   - Token-driven only — no hard-coded colors or shadows.
 *   - No DOM, JS, or PHP changes. All hooks and IDs preserved.
 *   - Layered after style.css; rules use !important only where Bootstrap
 *     or legacy style.css would otherwise win the cascade.
 *   - Dark mode comes for free via [data-theme="dark"] on existing tokens.
 *
 * Loaded from app/index.html after css/style.css and css/dashboard.css.
