/* Year-group picker: a six-up radio group styled as chunky tappable pills.
   Used on the parent-facing child form. The hidden radios stay as the
   form's source of truth, so the pills work without JS — the Stimulus
   child-form controller just toggles `checked` in response to DOB
   changes. Keyboard users can still tab into the radios and arrow-key
   between them. */
