/**
 * [WHO]: DatePicker composes a Spark trigger with the shared Calendar in a Popover.
 * [FROM]: React, date-fns, registry/basic/button, registry/basic/calendar, registry/basic/popover, registry/lib/utils.
 * [TO]: sparkdesign package consumers; output of CLI `add date-picker` when registered.
 * [HERE]: registry/basic/date-picker.tsx — Spark Design date picker source.
 *
 * [PROTOCOL]:
 * 1. Render a Button trigger that surfaces the selected date using project typography/tokens.
 * 2. Use the shared Calendar primitive inside a PopoverContent for the day grid; never fall back to native pickers.
 * 3. Follow design tokens and explicit type exports.
