/*
 * ProfileMenu — responsive dropdown / bottom-sheet for profile switching.
 *
 * Mobile-first: defaults to a full-width bottom-sheet that slides up from
 * the bottom edge of the viewport. A semi-transparent backdrop covers the
 * page content behind it.
 *
 * Desktop (>= 768px): transforms into a compact dropdown card anchored near
 * the user-area element — no backdrop, positioned via JS inline styles.
 *
 * All colours, spacing, and typography consume design-system.css variables
 * so the component adapts to both light and dark themes automatically.
