/**
 * Reusable City selector — shared combobox styling.
 *
 * Used by Patient Saved Address, Request Care location and Practitioner
 * Primary Service City. Values come from Design.md tokens (m3-tokens.css)
 * so the control matches the rest of the application.
 *
 * Mobile: the suggestion list is anchored to the control, bounded in height,
 * scrolls internally, and stacks ABOVE the fixed bottom navigation
 * (which sits at z-index 45). It is positioned absolutely so it can never
 * create page overflow, and the component clamps its height to the space
 * actually visible in the viewport — opening upward when dropping down would
 * run off the bottom of the screen.
