   Minimal Date — replaces the browser's built-in date picker with a
   calendar that matches the rest of the UI.

   Same contract as minimal-select: the original <input type="date">
   stays in the DOM as the value holder, so code reading/writing
   `.value` (YYYY-MM-DD) and listening for `change` is unaffected.
