/**
 * Header panels — the shared visual language for the three small
 * anchored-dropdown-on-desktop / bottom-sheet-on-mobile panels hanging
 * off the site header: the Quick Access menu (#headerMenuDropdown —
 * Dashboard/Admin Panel/Theme/Live connection), the Notification panel
 * (#notificationPanel — reminders), and the User/Profile menu (#userMenu).
 *
 * Quick Access's own open/close (the hamburger<->X icon swap, the theme-
 * swatch accordion) lives in index.html's inline script and is untouched;
 * Notification's and Profile's open/close both go through the shared
 * utils/header-panel.js controller. All three just apply the same .hp-*
 * classes below — visual/layout only, nothing here drives behavior.
 *
 * Desktop/tablet (>=768px): anchored dropdown, right-aligned below its
 * trigger button — glass background, 20px rounded corners, a soft two-tone
 * cyan/purple glow (the app's own logo gradient) instead of a flat border,
 * scale+fade entrance.
 *
 * Mobile (<768px): the same element becomes a bottom sheet — fixed, full
 * width, slides up from the bottom edge with a scrim behind it and a drag
 * handle for swipe-to-dismiss. Comfortable full-width row spacing instead
 * of the narrow anchored card's tighter padding.
